Introduction
Congratulations on your purchase of the Celestron
StarSeeker! The StarSeeker ushers in a whole new genera-
tion of computer automated technology. Simple and friendly to
use, the StarSeeker is up and running after locating just three
bright objects. It’s the perfect combination of power and porta-
bility. If you are new to astronomy, you may wish to start off by
using the StarSeeker’s built-in Sky Tour feature, which com-
mands the StarSeeker to find the most interesting objects in
the sky and automatically slews to each one. Or if you are an
experienced amateur, you will appreciate the comprehensive
database of over 4,000 objects, including customized lists of
all the best deep-sky objects, bright double stars, and vari-
able stars. No matter at what level you are starting out, the
StarSeeker will unfold for you and your friends all the wonders
of the Universe.
• Never leave the telescope unsupervised, either when
children are present or adults who may not be familiar with
the correct operating procedures of your telescope.

the most sophisticated and easy to use telescopes available
on the market today.
The StarSeeker reflectors (StarSeeker 114mm and 130mm)
come attached to the mount in the shipping box.To make them
fit, the tube and mount were packed very compactly at the
factory. DO NOT ATTEMPT TO REPOSITION THE MOUNT
TO ITS PROPER ORIENTATION BY HAND! Otherwise,
the gears and motors may be damaged. After removing the
assembly from the shipping box, reposition the tube and
mount as follows:
Take time to read through this manual before embarking on
your journey through the Universe. It may take a few observ-
ing sessions to become familiar with your StarSeeker, so you
should keep this manual handy until you have fully mastered
your telescope’s operation. The StarSeeker hand control has
built-in instructions to guide you through all the alignment
procedures needed to have the telescope up and running in
minutes. Use this manual in conjunction with the on-screen
instructions provided by the hand control. The manual gives
detailed information regarding each step as well as needed
reference material and helpful hints guaranteed to make your
observing experience as simple and pleasurable as possible.
1. Remove the tube from the mount by first removing the
thumbscrew on the mount’s clamp. Open the clamp, and
remove the tube.
2. Plug the hand controller and battery pack (with batteries
installed, requires 8x AA batteries) into the base of the
mount.
Your StarSeeker telescope is designed to give you years of
fun and rewarding observations. However, there are a few
things to consider before using your telescope that will ensure
your safety and protect your equipment.
3. Use the hand controller to select your telescope model
(see chart on page 10).
4. Now use the hand controller direction buttons to reposition
the mount until it is roughly in the position shown on page
4 of the instruction manual.
Warning
5. Replace the optical tube in the cradle and secure it with
the thumbscrew.
• Never look directly at the sun with the naked eye or
with a telescope (unless you have the proper solar filter).
Permanent and irreversible eye damage may result.
• Never use your telescope to project an image of the sun
onto any surface. Internal heat build-up can damage the
telescope and any accessories attached to it.
• Never use an eyepiece solar filter or a Herschel wedge.

2. Thread the coupling screw into the hole at the bottom of
the fork arm base and hand tighten.
Assembling the StarSeeker
Your StarSeeker comes in three major sections: the optical
tube, fork arm and the tripod. These sections can be attached
in seconds using the quick release coupling screw located
under the tripod mounting platform. Remove all of the acces-
sories from their individual boxes. Remember to save all of the
containers so that they can be used to transport the telescope.
Before attaching the visual accessories, the telescope tube
should be mounted to its tripod. First, install the accessory tray
onto the tripod legs:
Your StarSeeker is fully assembled and is ready to attach the
accessories.
1. Remove the tripod from the box and spread the legs apart
until the center leg brace is fully extended.
2. Locate the accessory tray, and place it on top of the tripod
center support brace in between the tripod legs (see figure
2-2).
3. Insert the locking bolt from underneath the tripod support
brace and thread it into the hole in the center of the acces-
sory tray. Do not over tighten.

Accessory tray
The accessory tray has a built-on hand control holder protrud-
ing from the side.The back of the hand control has an opening
that slides over the clip on the inside of the holder.

It is a good idea to adjust the height of the tripod before attach-
ing the fork arm and tube. Minor adjustments can be made
later. To adjust the height of the tripod legs:
The Star Diagonal
(For StarSeeker 70mm & 80mm Models Only)
1. Loosen the tripod leg locking bolt located on the side of
each leg.
The star diagonal diverts the light at a right angle from the light
path of the telescope. For astronomical observing, this allows
you to observe in positions that are more comfortable than if
you were to look straight through. To attach the star diagonal:
2. Slide the inner portion of each leg down 6" to 8" inches.
3. Tighten the tripod locking bolts to hold each leg in place.
1. Turn the thumbscrew on the eyepiece adapter at the end
of the focuser barrel until it no longer extends into (i.e.,
obstructs) the inner diameter of the focus barrel. Remove
the protective dust cap from the focuser barrel.
Attaching the Telescope to the Tripod
With the tripod properly assembled, the telescope tube and
fork arm can easily be attached using the quick release cou-
pling screw located underneath the tripod mounting platform:
2. Slide the chrome portion of the star diagonal into the eye-
piece adapter.
1. Hold the telescope tube assembly by the fork arm and
place the fork arm base inside the tripod mounting plat-
form. See Figure 2-1.
3. Tighten the thumbscrew on the eyepiece adapter to hold
the star diagonal in place.
Optical Tube
If you wish to change the orientation of the star diagonal,
loosen the thumbscrew on the eyepiece adapter until the star
diagonal rotates freely. Rotate the diagonal to the desired posi-
tion and tighten the thumbscrew.

The Eyepiece
The eyepiece, or ocular, is the optical element that magnifies
the image focused by the telescope. The eyepiece fits either
directly into the focuser (114mm and 130mm models) or into
the star diagonal (70mm and 80mm models). To install the
eyepiece:

Eyepieces are commonly referred to by focal length and barrel
diameter. The focal length of each eyepiece is printed on the
eyepiece barrel. The longer the focal length (i.e., the larger
the number), the lower the eyepiece power or magnification;
and the shorter the focal length (i.e., the smaller the num-
ber), the higher the magnification. Generally, you will use
low-to-moderate power when viewing. For more information
on how to determine power, see the section on “Calculating
Magnification.”
The Star Pointer Finderscope
The Star Pointer is the quickest and easiest way to point your
telescope exactly at a desired object in the sky. It’s like having
a laser pointer that you can shine directly onto the night sky.
The Star Pointer is a zero magnification pointing tool that uses
a coated glass window to superimpose the image of a small
red dot onto the night sky. While keeping both eyes open when
looking through the Star Pointer, simply move your telescope
until the red dot, seen through the Star Pointer, merges with
the object as seen with your unaided eye. The red dot is pro-
duced by a light-emitting diode (LED); it is not a laser beam
and will not damage the glass window or your eye. The Star
Pointer comes equipped with a variable brightness control, two
axes alignment control and mounting brackets. Before the Star
Pointer is ready to be used, it must be attached to the tele-
scope tube and properly aligned:
Barrel diameter is the diameter of the barrel that slides into the
star diagonal or focuser. The StarSeeker uses eyepieces with
a standard 1-1/4" barrel diameter.
Focusing
To focus your telescope, simply turn either of the focus knobs
at the eyepiece end of the optical tube (see figures 2-3 and
2.4). Turn the focus knob until the image is sharp. Once sharp,
turn the knob towards you to focus on an object that is clos-
er than the one you are currently observing. Turn the knob
away from you to focus on a more distant object than the one
you are currently observing.
Star Pointer Installation
For StarSeeker 80mm and 130mm models:
1. Slide the Star Pointer bracket into the dovetail mounting
platform near the focuser assembly.
2. Orient the Star Pointer so that the sight tube is facing
towards the front of the tube.
Eyepiece

3. Secure the Star Pointer bracket by tightening the thumb
screw on the mounting platform.
For StarSeeker 70mm and 114mm models:
1. Remove the nuts from the studs where the Star Pointer will
mount.

2. Mount the Star Pointer bracket by placing the bracket over
the studs protruding from the tube and tightening it down
with the supplied nuts. Orient the Star Pointer so that the
sight tube is facing towards the front of the tube.
Star Pointer Operation
Star diagonal
The star pointer is powered by a long life 3-volt lithium battery
(#CR2032) located underneath the front portion of the Star
Pointer. Like all finderscopes, the Star Pointer must be properly
aligned with the main telescope before it can be used. This is
a simple process using the azimuth and altitude control knobs
located on the side and bottom of the Star Pointer. The align-

Alignment Procedure
In order for the StarSeeker to accurately point to objects in the
sky, it must first be aligned to known positions (stars) in the
sky. With this information, the telescope can create a model of
the sky, which it uses to locate any object with known coordi-
nates. There are many ways to align the StarSeeker with the
sky depending on what infor-
mation the user is able to
provide: SkyAlign uses your

for basic information like the date, time and location. Then you
simply need to aim the telescope to any three bright celestial
objects in the sky. Since Sky Align requires no knowledge of
the night sky it is not necessary to know the name of the stars
at which you are aiming. You may even select a planet or the
moon. The StarSeeker is then ready to start finding and track-
ing any of the objects in its 4,000+ object database. Before
the telescope is ready to be aligned, it should be set up in an
outside location with all accessories (eyepiece, diagonal and
finderscope) attached and lens cover removed as described in
the Assembly section of the manual. To begin Sky Align:

Tips for Using Sky Align
Remember the following alignment guidelines to make using
Sky Align as simple and accurate as possible.
• Be sure to level the tripod before you begin alignment.
The time/site information along with a level tripod will help
the telescope better predict the available bright stars and
planets that are above the horizon.
5. Use the arrow buttons to slew the telescope to the star
you selected. Center the star in the finderscope and press
ENTER. Finally, center the star in the eyepiece and press
ALIGN.
• Remember to select alignment stars that are as far apart
in the sky as possible. For best results make sure that the
third alignment star does not lie in a straight line between
the first two stars. This may result in a failed alignment.
6. Based on this information, the StarSeeker will automati-
cally display the most suitable second alignment star that
is above the horizon. Press ENTER to automatically slew
the telescope to the displayed star. If for some reason you
do not wish to select this star (perhaps it is behind a tree
or building), you can either:
• Don’t worry about confusing planets for stars when
selecting alignment objects. SkyAlign works with the four
brightest planets (Venus, Jupiter, Saturn and Mars) as well
as the Moon. In addition to the planets, the hand control
has over 80 bright alignment stars to choose from (down
to 2.5 magnitude).
• Press the UNDO button to display the next most suitable
star for alignment.
• Rarely SkyAlign will not be able to determine what three
alignment objects were centered. This sometime happens
when a bright planet or the Moon passes near one of the
brighter stars. In situations like these it is best to try to
avoid aligning to either object if possible.
• Use the UP and DOWN scroll buttons to manually select
any star you wish from the entire list of available stars.
Once finished slewing, the display will ask you to use the
arrow buttons to align the selected star with the red dot of the
finderscope. Once centered in the finder, press ENTER. The
display will then instruct you to center the star in the field of
view of the eyepiece. When the star is centered, press ALIGN
to accept this star as your second alignment star. When the
telescope has been aligned to both stars the display will read
Align Success, and you are now ready to find your first object.
• Be sure to center the objects with the same final move-
ments as the direction of the GoTo Approach.For example,
if the scope normally finishes a GoTo with the front of the
scope moving right and up, you should center all three
alignment objects in the eyepiece using the right and up
arrow buttons (the up/down arrows reverse at slew rates
of 6 or lower). Approaching the star from this direction
when looking through the eyepiece will eliminate much
of the backlash between the gears and assure the most
accurate alignment possible.
Two Star Alignment
With the two-star alignment method, the StarSeeker requires
the user to know the positions of two bright stars in order to
accurately align the telescope with the sky and begin finding
objects. Here is an overview of the two-star alignment proce-

As with Sky Align, Auto Two-Star Align requires you to enter
all the necessary time/site information as before. Once this
information is entered, StarSeeker will prompt you to select
and point the telescope at one known star in the sky. The
StarSeeker now has all the information it needs to automati-
cally choose a second star that will assure the best possible
alignment. Once selected, the telescope will automatically
slew to that second alignment star to complete the align-
ment. With the StarSeeker set up outside with all accessories
attached and the tripod leveled, follow the steps below to align
the telescope:
1. Once the StarSeeker is powered on, use the Up and
Down scroll keys (10) to select Two-Star Align, and press
ENTER.
2. Press ENTER to accept the time/site information displayed
on the display, or press UNDO to enter new information.
3. The SELECT STAR 1 message will appear in the top row
of the display. Use the Up and Down scroll keys (10) to
select the star you wish to use for the first alignment star.
Press ENTER.

4. StarSeeker then asks you to center in the eyepiece the
alignment star you selected. Use the direction arrow but-
tons to slew the telescope to the alignment star and care-
fully center the star in the finderscope. Press ENTER when
centered.
Solar System Align
Solar System Align is designed to provide excellent tracking
and GoTo performance by using solar system objects (Sun,
Moon and planets) to align the telescope with the sky. Solar
System Align is a great way to align your telescope for day-
time viewing as well as a quick way to align the telescope for
night time observing.
5. Then, center the star in the eyepiece and press ALIGN.
HELPFUL HINT: In order to accurately center the alignment
star in the eyepiece, you may wish to decrease the slew rate
of the motors for fine centering. This is done by pressing the
RATE key (11) on the hand controller then selecting the num-
ber that corresponds to the speed you desire. (9 = fastest , 1
= slowest).
Never look directly at the sun with the naked eye or with a
telescope (unless you have the proper solar filter). Permanent
and irreversible eye damage may result.
1. Select Solar System Align from the alignment options.
2. Press ENTER to accept the time/site information displayed
on the display, or press UNDO to enter new information.
6. StarSeeker will then ask you to select and center a sec-
ond alignment star and press the ALIGN key. It is best to
choose alignment stars that are a good distance away
from one another. Stars that are at least 40° to 60° apart
from each other will give you a more accurate alignment
than stars that are close to each other.
3. The SELECT OBJECT message will appear in the top row
of the display. Use the Up and Down scroll keys (10) to
select the daytime object (planet, moon or sun) you wish
to align. Press ENTER.
4. StarSeeker then asks you to center in the eyepiece the
alignment object you selected. Use the direction arrow
buttons to slew the telescope to the alignment object and
carefully center it in the finderscope. Press ENTER when
centered.
Once the second star alignment is completed properly, the
display will read Align Successful, and you should hear the
tracking motors turn-on and begin to track.
One-Star Align
5. Then, center the object in the eyepiece and press ALIGN.
One-Star Align requires you to input all the same informa-
tion as you would for the Two-Star Align procedure. However,
instead of slewing to two alignment stars for centering and
alignment, the StarSeeker uses only one star to model the
sky based on the information given. This will allow you to
roughly slew to the coordinates of bright objects like the moon
and planets and gives the StarSeeker the information needed
to track objects in altazimuth in any part of the sky. One-Star
Align is not meant to be used to accurately locate small or
faint deep-sky objects or to track objects accurately for pho-
tography.
Once in position, the StarSeeker will model the sky based on
this information and display Align Successful.
Tips for Using Solar System Align
• For safety purposes, the Sun will not be displayed in
any of the hand control’s customer object lists unless it
is enabled from the Utilities Menu. To allow the Sun to be
displayed on the hand control, do the following:
1. Press the UNDO button until the display reads NexStar GT.
2. Press the MENU button and use the Up and Down keys to
select the Utilities menu. Press ENTER.
To use One-Star Align:
1. Select One-Star Align from the alignment options.
3. Use the UP and Down keys to select Sun Menu and press
ENTER.
2. Press ENTER to accept the time/site information displayed
on the display, or press UNDO to enter new information.
4. Press ENTER again to allow the Sun to appear on the
hand control display.
3. The SELECT STAR 1 message will appear in the top row
of the display. Use the Up and Down scroll keys (10) to
select the star you wish to use for the first alignment star.
Press ENTER.
The Sun can be removed from the display by using the same
procedure as above.
To improve the telescope pointing accuracy, you can use the
Re-Align feature as described below.
4. StarSeeker then asks you to center in the eyepiece the
alignment star you selected. Use the direction arrow but-
tons to slew the telescope to the alignment star and care-
fully center the star in the finderscope. Press ENTER when
centered.
StarSeeker Re-Alignment
The StarSeeker has a re-alignment feature which allows you
to replace either of the original alignment stars with a new star
or celestial object. This can be useful in several situations:
5. Then, center the star in the eyepiece and press ALIGN.
6. Once in position, the StarSeeker will model the sky based
• If you are observing over a period of a few hours, you
may notice that your original two alignment stars have
drifted towards the west considerably. (Remember that the
stars are moving at a rate of 15° every hour). Aligning on a
new star that is in the eastern part of the sky will improve
your pointing accuracy, especially on objects in that part
on this information and display Align Successful.
Note: Once a One-Star Alignment has been done, you can
use the Re-alignment feature (later in this section ) to improve
your telescope’s pointing accuracy.

of the sky.
required to enter the first four digits of the objects six digit SAO
number. Once the first four digits are entered, the hand control
will automatically list all the available SAO objects beginning
with those numbers. This allows you to scroll through only
the SAO stars in the database. For example, in searching for
the SAO star 40186 (Capella), the first four digits would be
“0401”. Entering this number will display the closest match
from the SAO stars available in the database. From there you
can scroll down the list and select the desired object.
• If you have aligned your telescope using the One-star
align method, you can use re-align to align to an additional
object in the sky. This will improve the pointing accuracy
of your telescope without having to re-enter addition infor-
mation.
To replace an existing alignment star with a new alignment
star:
1. Select the desired star (or object) from the database and
slew to it.
Slewing to an Object
Once the desired object is displayed on the hand control
screen, you have two options:
2. Carefully center the object in the eyepiece.
3. Once centered, press the UNDO button until you are at
the main menu.
• Press the INFO Key. This will give you useful information
about the selected object such as magnitude, constella-
tion and fascinating facts about many of the objects.
4. With NexStar GT displayed, press the ALIGN key on the
hand control.
• Press the ENTER Key. This will automatically slew the
telescope to the coordinates of the object. While the tele-
scope is slewing to the object, the user can still access
many of the hand control functions (such as displaying
information about the object).
5. The display will then ask you which alignment star you
want to replace.
6. Use the UP and Down scroll keys to select the alignment
star to be replaced, and press ENTER. It is usually best
to replace the star closest to the new object. This will
space out your alignment stars across the sky. If you have
used one of the single object alignment methods then it is
always best to replace the object that is “unassigned” with
an actual object.
If you slew to an object that is below the horizon, StarSeeker
will notify you by displaying a message reminding you that
you have selected an object outside of your slew limits (see
Slew Limits in the Scope Setup section of the manual). Press
UNDO to go back and select a new object. Press ENTER to
ignore the message and continue the slew. The StarSeeker
hand control will only display objects that are below the hori-
zon if the Filter Limits are set below 0° in altitude. See Filter
Limits in the Utility Feature section of the manual for more
information on setting the filter limits.
7. Press ALIGN to make the change.
Selecting an Object
Now that the telescope is properly aligned, you can choose
an object from any of the catalogs in the StarSeeker’s data-
base. The hand control has a key designated for each of the
catalogs in its database. There are two ways to select objects
from the database; scrolling through the named object lists
and entering object numbers:
Caution: Never slew the telescope when someone is
looking into the eyepiece.The telescope can move at fast
slew speeds and may hit an observer in the eye.
Object information can be obtained without having to do a
star alignment. After the telescope is powered on, pressing
any of the catalog keys allows you to scroll through object lists
or enter catalog numbers and view the information about the
object as described above.
• Pressing the LIST key on the hand control will access
all objects in the database that have common names or
types. Each list is broken down into the following catego-
ries: Named Stars, Named Object, Double Stars, Variable
Stars and Asterisms. Selecting any one of these options
will display an alpha-numeric listing of the objects under
that list. Pressing the Up and Down keys (10) allows you
to scroll through the catalog to the desired object.
Finding Planets
The StarSeeker can locate all 8 of our solar systems planets
plus the Sun and Moon. However, the hand control will only
display the solar system objects that are above the horizon (or
within its filter limits).To locate the planets, press the PLANET
key on the hand control. The hand control will display all solar
system objects that are above the horizon:
• Pressing any of the catalog keys (M, CALD, NGC, or
STAR) will display a blinking cursor below the name of
the catalog chosen. Use the numeric key pad to enter the
number of any object within these standardized catalogs.
For example, to find the Orion Nebula, press the “M” key
and enter “042”.
• Use the Up and Down keys to select the planet that you
wish to observe.
• Pressing the PLANET button will allow you to use the
UP and DOWN arrow keys to scroll through and select the
eight planets as well as the moon.
• Press INFO to access information on the displayed planet.
• Press ENTER to slew to the displayed planet.
To allow the Sun to be displayed as an option in the database,
see Sun Menu in the Utilities section of the manual.
When scrolling through a long list of objects, holding down
either the Up or Down key will allow you to scroll through the
catalog at a rapid speed.
When entering the number for a SAO star, you are only

Tour Mode
The hand control has a “double button” feature that allows you
to instantly speed up the motors without having to choose a
speed rate. To use this feature, simply press the arrow button
that corresponds to the direction that you want to move the
telescope. While holding that button down, press the opposite
directional button. This will increase the speed to the maxi-
mum slew rate.
The StarSeeker includes a tour feature which automatically
allows the user to choose from a list of interesting objects
based on the date and time in which you are observing. The
automatic tour will display only those objects that are with-
in your set filter limits. To activate the Tour mode, press the
TOUR key on the hand control. The StarSeeker will display
the best objects to observe that are currently in the sky.
When using the Up and Down buttons on the StarSeeker
70mm or 80mm, the slower slew rates (6 and lower) move
the motors in the opposite direction than the faster slew rates
(7- 9). This is done so that an object will move in the appro-
priate direction when looking into the eyepiece (i.e. pressing
the up arrow button will move the star upwards in the field of
view of the eyepiece). However, if any of the slower slew rates
(rate 6 and below) are used to center an object in the Star
Pointer, you may need to press the opposite directional button
to make the telescope move in the correct direction.
• To see information and data about the displayed object,
press the INFO key.
• To slew to the object displayed, press ENTER.
• To see the next tour object, press the Down key.
Constellation Tour
In addition to the Tour Mode, the StarSeeker telescope has
a Constellation Tour that allows the user to take a tour of all
the best objects within a particular constellation. Selecting
Constellation from the LIST menu will display all the constel-
lation names that are above the user defined horizon (filter
limits). Once a constellation is selected, you can choose from
any of the database object catalogs to produce a list of all the
available objects in that constellation.
Set Up Procedures
The StarSeeker contains many user defined setup functions
designed to give the user control over the telescope’s many
advanced features. All of the set up and utility features can be
accessed by pressing the MENU key and scrolling through
the options:
• To see information and data about the displayed object,
press the INFO key.
Tracking Mode-Once the StarSeeker is aligned the tracking
motors will automatically turn on and begin tracking the sky.
However, the tracking can be turned off for terrestrial use:
• To slew to the object displayed, press ENTER.
• To see the next tour object, press the Up key.
Alt-Az This is the default tracking rate and is used when
the telescope has been properly aligned.
Direction Buttons
The StarSeeker has four direction buttons in the center of the
hand control which controls the telescope motion in altitude
(up and down) and azimuth (left and right).The telescope can
be controlled at nine different speed rates.
EQ North Used to track the sky when the telescope is
polar aligned using an equatorial wedge in the Northern
Hemisphere. This option is not used with the StarSeeker
series of telescopes.
EQ South Used to track the sky when the telescope is
polar aligned using an equatorial wedge in the Southern
Hemisphere. This option is not used with the StarSeeker
series of telescopes.
1 = 2x
2 = 4x
3 = 8x
4 = 16x
5 = 32x
6 = .5° / sec
7 = 1° / sec
8 = 2° / sec
Off When using the telescope for terrestrial (land) obser-
vation the tracking can be turned off so that the telescope
never moves.
9 = 4° / sec
Nine available slew speeds
Rate Button
Note: The EQ North and EQ South tracking modes are
only needed with telescopes that can be polar aligned. The
StarSeeker’s are exclusively Alt-Az mounted telescopes and
do not require equatorial tracking.
Pressing the RATE key (11) allows you to instantly change the
speed rate of the motors from high speed slew rate to precise
guiding rate or anywhere in between. Each rate corresponds
to a number on the hand controller key pad. The number 9 is
the fastest rate (approximately 4° per second, depending on
power source) and is used for slewing between objects and
locating alignment stars. The number 1 on the hand control
is the slowest rate (2x sidereal) and can be used for accurate
centering of objects in the eyepiece. To change the speed
rate of the motors:
Tracking Rate - In addition to being able to move the tele-
scope with the hand control buttons, the StarSeeker will
continually track a celestial object as it moves across the
night sky. The tracking rate can be changed depending on
what type of object is being observed:
Sidereal This rate compensates for the rotation of the earth
by moving the telescope at the same rate as the rotation of
the earth, but in the opposite direction. When tracking in Alt-
Az mode, the telescope must make corrections in both altitude
and azimuth.
• Press the RATE key on the hand control. The LCD will
display the current speed rate.
• Press the number on the hand control that corresponds
to the desired speed.

Lunar Used for tracking the moon when observing the lunar
Identify
landscape.
Identify Mode will search any of the StarSeeker database
catalogs or lists and display the name and offset distances to
the nearest matching objects. This feature can serve two pur-
poses. First, it can be used to identify an unknown object in
the field of view of your eyepiece. Additionally, Identify Mode
can be used to find other celestial objects that are close to
the objects you are currently observing. For example, if your
telescope is pointed at the brightest star in the constellation
Lyra, choosing Identify and then searching the Named Star
catalog will no doubt return the star Vega as the star you are
observing. However, by selecting Identify and searching by
the Named Object or Messier catalogs, the hand control will
let you know that the Ring Nebula (M57) is approximately 6°
from your current position. Searching the Double Star catalog
will reveal that Epsilon Lyrae is only 1° away from Vega. To
use the Identify feature:
Solar Used for tracking the Sun when solar observing using
a proper solar filter.
View Time-Site - View Time-Site will display the last saved
time and longitude/latitude entered in the hand control.
User Defined Objects - The StarSeeker can store up to 50
different user defined objects in its memory. The objects can
be daytime land objects or an interesting celestial object that
you discover that is not included in the regular database.
There are several ways to save an object to memory depend-
ing on what type of object it is:
Save Sky Object: The StarSeeker stores celestial objects to
its database by saving its right ascension and declination in
the sky. This way the same object can be found each time
the telescope is aligned. Once a desired object is centered
in the eyepiece, simply scroll to the Save Sky Obj command
and press ENTER. The display will ask you to enter a number
between 1-25 to identify the object. Press ENTER again to
save this object to the database.
• Press the Menu button and select the Identify option.
• Use the Up/Down scroll keys to select the catalog that
you would like to search.
• Press ENTER to begin the search.
Save Database (Db) Object: This feature allows you to cre-
ate your own custom tour of database objects by allowing
you to record the current position of the telescope and save
the name of the object by selecting it from any one of the
database catalogs. These objects then can be accessed by
selecting GoTo Sky Object.
Note: Some of the databases contain thousands of
objects, and can therefore take a minute or two to return
the closest object.
Scope Setup Features
SetupTime-Site - Allows the user to customize the StarSeeker
display by changing time and location parameters (such as
time zone and daylight savings).
Save Land Object: The StarSeeker can also be used as a
spotting scope on terrestrial objects. Fixed land objects can
be stored by saving their altitude and azimuth relative to the
location of the telescope at the time of observing. Since these
objects are relative to the location of the telescope, they are
only valid for that exact location. To save land objects, once
again center the desired object in the eyepiece. Scroll down
to the Save Land Obj command and press ENTER. The display
will ask you to enter a number between 1-25 to identify the
object. Press ENTER again to save this object to the data-
base.
Anti-backlash - All mechanical gears have a certain amount
of backlash or play between the gears. This play is evident
by how long it takes for a star to move in the eyepiece when
the hand control arrow buttons are pressed (especially when
changing directions). The StarSeeker’s anti-backlash features
allows the user to compensate for backlash by inputting a
value which quickly rewinds the motors just enough to elimi-
nate the play between gears. The amount of compensation
needed depends on the slewing rate selected; the slower the
slewing rate the longer it will take for the star to appear to
move in the eyepiece. Therefore, the anti-backlash compen-
sation will have to be set higher. You will need to experiment
with different values; a value between 20 and 50 is usually
best for most visual observing, whereas a higher value may
be necessary for photographic guiding. Positive backlash
compensation is applied when the mount changes its direction
of movement from backwards to forwards. Similarly, negative
backlash compensation is applied when the mount changes
its direction of movement from forwards to backwards. When
tracking is enabled, the mount will be moving in one or both
axes in either the positive or negative direction, so backlash
compensation will always be applied when a direction button
is released and the direction moved is opposite to the direc-
tion of travel.
Enter R.A. - Dec: You can also store a specific set of coordi-
nates for an object just by entering the R.A. and declination
for that object. Scroll to the Enter RA-DEC command and press
ENTER. The display will then ask you to enter first the R.A.
and then the declination of the desired object.
GoTo Object: To go to any of the user defined objects stored
in the database, scroll down to either GoTo Sky Obj or Goto Land
Obj and enter the number of the object you wish to select and
press ENTER. StarSeeker will automatically retrieve and dis-
play the coordinates before slewing to the object.
To replace the contents of any of the user defined objects,
simply save a new object using one of the existing identifi-
cation numbers; StarSeeker will replace the previous user
defined object with the current one.
Get RA/DEC - Displays the right ascension and declination
To set the anti-backlash value, scroll down to the anti-back-
lash option and press ENTER. Enter a value from 0-100 for
both azimuth and altitude directions and press ENTER after
each one to save these values. StarSeeker will remember
for the current position of the telescope.
Goto R.A/ Dec - Allows you to input a specific R.A. and dec-
lination and slew to it.

these values and use them each time it is turned on until they
are changed.
Utility Features
Version - Selecting this option will allow you to see the version
number of the hand control software.
Slew Limits - Sets the limits in altitude that the telescope can
slew without displaying a warning message. The slew limits
prevent the telescope tube from slewing to an object below the
horizon or slewing to an object that is high enough that the tube
might hit one of the tripod legs. However, the slew limits can
be customized depending on your needs. For example, if you
would like to slew to an object that is close to the zenith and are
certain that the tube will not hit the tripod legs, you can set the
slew limits to 90° in altitude.This will allow the telescope to slew
to any object above the horizon without warning.
Light Control - This feature allows you to turn off both the
red key pad light and LCD display for daytime use to conserve
power and to help preserve your night vision.
Factory Setting - Returns the StarSeeker hand control
to its original factory setting. Parameters such as backlash
compensation values, initial date and time, longitude/latitude
along with slew and filter limits will be reset. However, stored
parameters such as PEC and user defined objects will remain
saved even when Factory Settings is selected. The hand con-
trol will ask you to press the “0” key before returning to the
factory default setting.
Filter Limits - When an alignment is complete, the StarSeeker
automatically knows which celestial objects are above the
horizon. As a result, when scrolling through the database lists
(or selecting the Tour function), the StarSeeker hand control
will display only those objects that are known to be above the
horizon when you are observing.You can customize the object
database by selecting altitude limits that are appropriate for
your location and situation. For example, if you are observ-
ing from a mountainous location where the horizon is partially
obscured, you can set your minimum altitude limit to read +20°.
This will make sure that the hand control only displays objects
that are higher in altitude than 20°.
Get Alt-Az - Displays the relative altitude and azimuth for the
current position of the telescope.
Goto Alt-Az - Allows you to enter a specific altitude and azi-
muth position and slew to it.
Hibernate - Hibernate allows the StarSeeker to be completely
powered down and still retain its alignment when turned back
on. This not only saves power, but is ideal for those that have
their telescopes permanently mounted or leave their telescope
in one location for long periods of time.To place your telescope
in Hibernate mode:
If you want to explore the entire object database, set the maxi-
mum altitude limit to 90° and the minimum limit to -90°.This will
display every object in the database lists regardless of whether
it is visible in the sky from your location or not.
1. Select Hibernate from the Utility Menu.
2. Move the telescope to a desire position and press ENTER.
3. Power off the telescope. Remember to never move your
telescope manually while in Hibernate mode.
Direction Buttons -The direction a star moves in the eyepiece
varies depending on the accessories being used. This can cre-
ate confusion when guiding on a star using an off-axis guider
versus a straight through guide scope. To compensate for this,
the direction of the drive control keys can be changed. To
reverse the button logic of the hand control, press the MENU
button and select Direction Buttons from the Utilities menu. Use
the Up/Down arrow keys (10) to select either the Azimuth but-
tons (left and right) or Altitude buttons (up and down) and press
ENTER. Pressing ENTER again will reverse the direction of the
hand control buttons from their current state. Direction Buttons
will only change the eyepiece rates (rate 1-6) and will not affect
the slew rates (rate 7-9).
Once the telescope is powered on again the display will read
Wake Up. After pressing Enter you have the option of scrolling
through the time/site information to confirm the current setting.
Press ENTER to wake up the telescope.
Pressing UNDO at the Wake Up screen allows you to explore
many of the features of the hand control without waking the
telescope up from hibernate mode. To wake up the telescope
after UNDO has been pressed, select Hibernate from the Utility
menu and press ENTER. Do not use the direction buttons to
move the telescope while in hibernate mode.
Sun Menu
Select Model - The first time the StarSeeker is powered on,
the hand control display allows you to select your StarSeeker
from a list of different models. If for some reason the incorrect
model was selected or you wish to use your hand control on
a different StarSeeker model, the Select Model utility feature
allows you to re-select the proper StarSeeker model from the
displayed list. Once the correct StarSeeker model has been
selected the power needs to be restarted before beginning the
alignment procedure. The Select Model feature will return the
hand control to its original factory settings. Parameters such
as backlash compensation values along with slew and filter
limits will be reset. However, stored parameters such as user
defined objects will remain saved even after the model has
been changed.
For safety purposes the Sun will not be displayed as a database
object unless it is first enabled. The enable the Sun, go to the
Sun Menu and press ENTER. The Sun will now be displayed
in the Planets catalog as can be used as an alignment object
when using the Solar System Alignment method. To remove
the Sun from displaying on the hand control, once again select
the Sun Menu from the Utilities Menu and press ENTER.
Scrolling Menu
This menus allows you to change the rate of speed that the text
scrolls across the hand control display.

Let’s say, for example, you are using the 25mm eyepiece. To
determine the magnification you simply divide the focal length
of your telescope (for example, the StarSeeker 130mm has
a focal length of 650mm) by the focal length of the eyepiece,
25mm. Dividing 650 by 25 yields a magnification of 26 power.
Telescope Basics
A telescope is an instrument that collects and focuses light.
The nature of the optical design determines how the light
is focused. Some telescopes, known as refractors, use
lenses. Other telescopes, known as reflectors, use mirrors.
The StarSeeker 70mm and 80mm telescopes are refrac-
tor telescopes that use an objective lens to collect light. The
StarSeeker 114mm and 130mm are reflecting telescopes with
a primary and secondary mirror to gather and focus light.
Although the power is variable, each instrument under aver-
age skies has a limit to the highest useful magnification. The
general rule is that 60 power can be used for every inch of
aperture. For example, the StarSeeker 80mm is 3.2" (80mm)
in diameter. Multiplying 3.2 by 60 gives a maximum useful
magnification of 192 power. Although this is the maximum
useful magnification, most observing is done in the range of
20 to 35 power for every inch of aperture which is 64 to 112
times for the StarSeeker 80mm telescope.
Focusing
Once you have found an object in the telescope, turn the
focusing knob until the image is sharp.To achieve a truly sharp
focus, never look through glass windows or across objects
that produce heat waves, such as asphalt parking lots.
Determining Field of View
Determining the field of view is important if you want to get
an idea of the angular size of the object you are observing. To
calculate the actual field of view, divide the apparent field of
the eyepiece (supplied by the eyepiece manufacturer) by the
magnification. In equation format, the formula looks like this:
For astronomical viewing, out of focus star images are very
diffuse, making them difficult to see. If you turn the focus knob
too quickly, you can go right through focus without seeing the
image. To avoid this problem, your first astronomical target
should be a bright object (like the Moon or a planet) so that
the image is visible even when out of focus.
Apparent Field of Eyepiece
True Field =
Image Orientation
The image orientation of any telescope changes depending
on how the eyepiece is inserted into the telescope. When
observing through the StarSeeker 70mm or 80mm using a
diagonal, the image will be right side up, but reversed from
left to right. When observing straight through, with the eye-
piece inserted directly into the telescope, the image will be
inverted.
Magnification
As you can see, before determining the field of view, you must
calculate the magnification. Using the example in the previous
section, we can determine the field of view using the same
25mm eyepiece.The 25mm eyepiece has an apparent field of
view of 56°. Divide the 56° by the magnification, which is 26
power. This yields an actual field of view of 2.2°.
When observing through the StarSeeker 114mm or 130mm,
a reflecting telescope, the image will appear up-side-down
when looking through the eyepiece.
To convert degrees to feet at 1,000 yards, which is more use-
ful for terrestrial observing, simply multiply by 52.5. Continuing
with our example, multiply the angular field 2.2° by 52.5. This
produces a linear field width of 115.5 feet at a distance of
one thousand yards. The apparent field of each eyepiece that
Celestron manufactures is found in the Celestron Accessory
Catalog (#93685).

General Observing Hints
When working with any optical instrument, there are a few
things to remember to ensure you get the best possible
image:
Calculating Magnification
You can change the power of your telescope just by changing
the eyepiece (ocular). To determine the magnification of your
telescope, simply divide the focal length of the telescope by
the focal length of the eyepiece used. In equation format, the
formula looks like this:
• Never look through window glass. Glass found in house-
hold windows is optically imperfect, and as a result, may
vary in thickness from one part of a window to the next.
This inconsistency can and will affect the ability to focus
your telescope. In most cases you will not be able to
achieve a truly sharp image, while in some cases, you
may actually see a double image.

• Never look across or over objects that are producing
heat waves.This includes asphalt parking lots on hot sum-
mer days or building rooftops.

• Hazy skies, fog, and mist can also make it difficult to
focus when viewing terrestrially.The amount of detail seen
under these conditions is greatly reduced. Also, when
photographing under these conditions, the processed film
may come out a little grainier than normal with lower con-
trast and underexposed.

ditionsareusually

tor on how much

• If you wear corrective lenses (specifically glasses), you
may want to remove them when observing with an eye-
piece attached to the telescope. When using a camera,
however, you should always wear corrective lenses to
ensure the sharpest possible focus. If you have astigma-
tism, corrective lenses must be worn at all times.
the horizon or when they are directly over a source of radi-
ating heat, such as a rooftop or chimney. See the “Seeing
Conditions” section later in this section.
Celestial Observing
With your telescope set up, you are ready to use it for observ-
ing. This section covers visual observing hints for both solar
system and deep sky objects as well as general observing
conditions which will affect your ability to observe.
• To increase contrast and bring out detail on the planetary
surface, try using color eyepiece filters.
Observing the Sun
Observing the Moon
Although overlooked by many amateur astronomers, solar
observation is both rewarding and fun. However, because
the Sun is so bright, special precautions must be taken when
observing our star so as not to damage your eyes or your
telescope.
Often, it is tempt-
ing to look at the
Moon when it is
full. At this time,
the face we see
is fully illuminated
and its light can
be overpowering.
In addition, little
or no contrast
can be seen dur-
ing this phase.
Never project an image of the Sun through the telescope.
Tremendous heat build-up may result inside the optical tube.
This can damage the telescope and/or any accessories
attached to the telescope.
For safe solar viewing, use a solar filter that reduces the
intensity of the Sun’s light, making it safe to view. With a filter
you can see sunspots as they move across the solar disk and
faculae, which are bright patches seen near the Sun’s edge.
One of the best
times to observe the Moon is during its partial phases (around
the time of first or third quarter). Long shadows reveal a great
amount of detail on the lunar surface. At low power you will
be able to see most of the lunar disk at one time. Change to
higher power (magnification) to focus in on a smaller area.
Choose the lunar tracking rate from the StarSeeker’s MENU
tracking rate options to keep the moon centered in the eye-
piece even at high magnifications.
Solar Observing Hints
• The best time to observe the Sun is in the early morning
or late afternoon when the air is cooler.
• To center the Sun without looking into the eyepiece,
watch the shadow of the telescope tube until it forms a
circular shadow.
• To ensure accurate tracking, be sure to select solar
tracking rate.
Lunar Observing Hints
• To increase contrast and bring out detail on the lunar surface,
use eyepiece filters. A yellow filter works well at improving
contrast while a neutral density or polarizing filter will reduce
overall surface brightness and glare.
Observing Deep Sky Objects
Deep sky objects are simply those objects outside the bound-
aries of our solar system.They include star clusters, planetary
nebulae, diffuse nebulae, double stars and other galaxies out-
side our own Milky Way. Most deep sky objects have a large
angular size. Therefore, low-to-moderate power is all you
need to see them. Visually, they are too faint to reveal any of
the color seen in long exposure photographs. Instead, they
appear black and white. And, because of their low surface
brightness, they should be observed from a dark sky location.
Light pollution around large urban areas washes out most
nebulae making them difficult, if not impossible, to observe.
Light Pollution Reduction filters help reduce the background
sky brightness, thus increasing contrast.
Observing the Planets
Other fascinating targets include the five naked eye planets.
You can see Venus go through its lunar-like phases. Mars can
reveal a host of surface detail and one, if not both, of its polar
caps.You will be able to see the cloud belts of Jupiter and the
great Red Spot (if it is visible at the time you are observing).
In addition, you will also be able to see the moons of Jupiter
as they orbit the giant planet. Saturn, with its beautiful rings, is
easily visible at moderate power.

Viewing Conditions
Telescope Maintenance
Viewing conditions affect what you can see through your
telescope during an observing session. Conditions include
transparency, sky illumination, and seeing. Understanding
viewing conditions and the effect they have on observing will
help you get the most out of your telescope.
While your StarSeeker telescope requires little maintenance,
there are a few things to remember that will ensure your tele-
scope performs at its best.
Care and Cleaning of the Optics
Transparency
Occasionally, dust and/or moisture may build up on the lenses
of your telescope. Special care should be taken when clean-
ing any instrument so as not to damage the optics.
Transparency is the clarity of the atmosphere which is affected
by clouds, moisture, and other airborne particles.Thick cumu-
lus clouds are completely opaque while cirrus can be thin,
allowing the light from the brightest stars through. Hazy skies
absorb more light than clear skies making fainter objects hard-
er to see and reducing contrast on brighter objects. Aerosols
ejected into the upper atmosphere from volcanic eruptions
also affect transparency. Ideal conditions are when the night
sky is inky black.
If dust has built up on a lens surface, remove the dust with a
brush (made of camel’s hair) or a can of pressurized air. Spray
at an angle to the lens for approximately two to four seconds.
Then, use an optical cleaning solution and optical cleaning
tissue to remove any remaining debris. Apply the solution to
the tissue and then apply the tissue paper to the lens. Low
pressure strokes should go from the center of the lens to the
outer portion. Do NOT rub in circles!
Sky Illumination
General sky brightening caused by the Moon, aurorae, nat-
ural airglow, and light pollution greatly affect transparency.
While not a problem for the brighter stars and planets, bright
skies reduce the contrast of extended nebulae making them
difficult, if not impossible, to see.To maximize your observing,
limit deep sky viewing to moonless nights far from the light
polluted skies found around major urban areas. LPR filters
enhance deep sky viewing from light polluted areas by block-
ing unwanted light while transmitting light from certain deep
sky objects.You can, on the other hand, observe planets and
stars from light polluted areas or when the Moon is out.
You can use a commercially made lens cleaner or mix your
own. A good cleaning solution is isopropyl alcohol mixed with
distilled water. The solution should be 60% isopropyl alcohol
and 40% distilled water. Or, liquid dish soap diluted with water
(a couple of drops per one quart of water) can be used.
To minimize the need to clean your telescope, replace all lens
covers once you have finished using it. This will prevent con-
taminants from entering the optical tube.
Collimation
(For StarSeeker 114mm and 130mm)
Seeing
The optical performance of your StarSeeker telescope is
directly related to its collimation, which is the alignment of its
optical system.Your StarSeeker was collimated at the factory
after it was completely assembled. However, if the telescope
is dropped or jarred severely during transport, it may have to
be collimated. The StarSeeker 70mm and 80mm are refrac-
tor-type telescopes that have fixed optical systems that
should not come out of collimation. The StarSeeker 114mm
and 130mm, however, have collimation screws that can be
used to adjust the alignment of the primary mirror.
Seeing conditions refers to the stability of the atmosphere
and directly affects the amount of fine detail seen in extend-
ed objects. The air in our atmosphere acts as a lens which
bends and distorts incoming light rays. The amount of bend-
ing depends on air density. Varying temperature layers have
different densities and, therefore, bend light differently. Light
rays from the same object arrive slightly displaced creating
an imperfect or smeared image. These atmospheric distur-
bances vary from time-to-time and place-to-place. The size
of the air parcels compared to your aperture determines the
“seeing” quality. Under good seeing conditions, fine detail is
visible on the brighter planets like Jupiter and Mars, and stars
are pinpoint images. Under poor seeing conditions, images
are blurred and stars appear as blobs.
To check if your telescope is in collimation refer to figure 6-1.
If you look into the eyepiece adapter (without an eyepiece) at
the top of the focuser, this is what you should see. If the reflec-
tion of your eye is off center, then collimating is necessary.
The StarSeeker 114mm and 130mm reflectors come with a
collimating cap. This is a simple cap that fits on the focuser
drawtube like a dust cap, but has a hole in the center and a
silver bottom. This helps center your eye so that collimating is
easy to perform.
The conditions described here apply to both visual and photo-
graphic observations.
In addition to the collimating cap, you’ll notice a small ring
label on the exact center of the primary mirror. This “center
mark” allows you to achieve a very precise alignment of the
primary mirror; you don’t have to guess where the center of
the mirror is. You simply adjust the primary mirror position
(described below) until the reflection of the hole in the col-
limating cap (the “dot”) is centered inside the ring.
Figure 5-1. Seeing conditions directly affect quality. These
drawings represent a point source (i.e., star) under bad seeing
conditions (right). Most often, seeing conditions produce images that
lie some where between these two extremes.

how to adjust the screw pairs to center the dot of the collimat-
ing cap in the ring of the primary mirror mark. Once the dot is
centered in the ring, the telescope is collimated, and the rear
cover plate can be reinstalled on the back of the mirror cell.
Support

Figure 6-1. The view of a collimated telescope as seen through
the focuser of the StarSeeker 114mm and 130mm reflectors.
NOTE: The center ring sticker need not ever be removed
from the primary mirror. Because it lies directly in the
shadow of the secondary mirror, its presence in no way
adversely affects the optical performance of the telescope
or the image quality. That might seem counter-intuitive,
but it’s true!
Collimating the StarSeeker 114mm
Adjustments to the collimation of the telescope can be made
by turning the collimation adjustment knobs located at the
rear of the optical tube (Figure 6-2). First loosen the three
Phillips head screws on the rear cell of the tube. Turn each
collimation knob, one at a time, until the reflected image of the
collimating cap’s dot in the secondary mirror is centered in the
primary mirror center mark ring. Once the telescope is col-
limated, tighten the Phillips head screws until you feel a slight
resistance. Do not over tighten the screws.
Collimation
screws
Figure 6-2. Collimation adjustment screws for the StarSeeker
114mm and 130mm.
Collimating the StarSeeker 130mm
To perform collimation adjustments, the rear cover plate must
first be removed. This is done by unthreading the three small
Phillips-head screws on the back of the mirror cell (Figure
6-3). Once the cover plate is removed, the collimation adjust-
ment screws are accessible (Figure 6-4).
Rear cover plate
Collimation screw pairs
Collimation adjustments are made by adjusting the three pairs
of collimation screws (Figure 6-4). The collimation screws can
be turned with a Phillips head screwdriver and a 2.5mm hex
key.Each pair of collimation screws work together to adjust the
alignment of the primary mirror; one screw must be loosened
and the other tightened by the same amount. Try tighten-
ing and loosening one of the pairs of collimation screws by
one turn. Look into the focuser to see if the secondary mirror
reflection has moved closer to the center of the primary mirror
reflection. The collimating cap makes this easy to see; watch
if the “dot” of the collimating cap is moving closer or farther
away from the ring on the center of the primary mirror. Repeat
this process on the other two pairs of collimation screws, if
necessary. It will take a little trial and error to get a feel for
Figure 6-3. To access the
collimation adjustment screws,
the rear cover plate must first
be removed.

Binary Stars: Binary (Double) stars are pairs of stars
that, because of their mutual gravitational attraction, orbit
around a common center of mass. If a group of three or
more stars revolve around one another, it is called a mul-

of all stars belong to binary or multiple systems. Systems
with individual components that can be seen separately by
a telescope are called visual binaries or visual multiples.

Magnitude: Magnitude is a measure of the brightness of a
celestial body.The brightest stars are assigned magnitude
1 and those increasingly fainter from 2 down to magnitude

1 is 2.5 times brighter than a star of magnitude 2, and
100 times brighter than a magnitude 5 star. The brightest
star, Sirius, has an apparent magnitude of -1.6, the full
moon is -12.7, and the Sun’s brightness, expressed on a

Reflector: A telescope in which the light is collected by
means of a mirror.
Resolution: The minimum detectable angle an optical
system can detect. Because of diffraction, there is a limit
to the minimum angle, resolution. The larger the aperture,
the better the resolution.

North celestial pole and ends at the South celestial pole
and passes through the zenith. If you are facing South, the
meridian starts from your Southern horizon and passes
directly overhead to the North celestial pole.

tial object measured in hours, minutes, and seconds along
the Celestial Equator eastward from the Vernal Equinox.
Messier: A French astronomer in the late 1700’s who

fuse objects and so Messier cataloged objects that were
not comets to help his search. This catalog became the
Messier Catalog, M1 through M110.

any celestial object that has a cloudy appearance.
Terminator: The boundary line between the light and dark
portion of the moon or a planet.
North Celestial Pole: The point in the Northern hemi-
sphere around which all the stars appear to rotate. This is
caused by the fact that the Earth is rotating on an axis that
passes through the North and South celestial poles. The
star Polaris lies less than a degree from this point and is
therefore referred to as the “Pole Star”.
Universe: The totality of astronomical things, events, rela-
tions and energies capable of being described objectively.
Nova: Although Latin for “new” it denotes a star that sud-
denly becomes explosively bright at the end of its life cycle.

Open Cluster: One of the groupings of stars that are con-
centrated along the plane of the Milky Way. Most have an
asymmetrical appearance and are loosely assembled.
They contain from a dozen to many hundreds of stars.
Waning Moon: The period of the moon’s cycle between
full and new, when its illuminated portion is decreasing.
Waxing Moon: The period of the moon’s cycle between
new and full, when its illuminated portion is increasing.
Parallax: Parallax is the difference in the apparent posi-
tion of an object against a background when viewed by
an observer from two different locations. These positions
and the actual position of the object form a triangle from
which the apex angle (the parallax) and the distance of
the object can be determined if the length of the baseline
between the observing positions is known and the angular
direction of the object from each position at the ends of
the baseline has been measured. The traditional method
in astronomy of determining the distance to a celestial
object is to measure its parallax.
Z -
Zenith: The point on the Celestial Sphere directly above
the observer.
Zodiac: The zodiac is the portion of the Celestial Sphere
that lies within 8 degrees on either side of the Ecliptic.The
apparent paths of the Sun, the Moon, and the planets,
with the exception of some portions of the path of Pluto,
lie within this band. Twelve divisions, or signs, each 30
degrees in width, comprise the zodiac. These signs coin-
cided with the zodiacal constellations about 2,000 years
ago. Because of the Precession of the Earth’s axis, the
Vernal Equinox has moved westward by about 30 degrees
since that time; the signs have moved with it and thus no
longer coincide with the constellations.
Parfocal: Refers to a group of eyepieces that all require
the same distance from the focal plane of the telescope
to be in focus. This means when you focus one parfocal
eyepiece all the other parfocal eyepieces, in a particular
line of eyepieces, will be in focus.
Parsec: The distance at which a star would show paral-
lax of one second of arc. It is equal to 3.26 light-years,
206,265 astronomical units, or 30,8000,000,000,000 km.
(Apart from the Sun, no star lies within one parsec of us.)
Point Source: An object which cannot be resolved into an
image because it to too far away or too small is considered
a point source. A planet is far away but it can be resolved
as a disk. Most stars cannot be resolved as disks, they are
too far away.
