TELESCOPE FEATURES
Take the time to become acquainted with all of these controls before attempting observations
through the telescope.
³ Focus Knob: Moves the telescope’s focus drawtube in a finely-controlled motion to achieve
precise image focus. Rotate the focus knob clockwise to focus on distant objects, and
counterclockwise to focus on nearby objects.
ᕢ Eyepiece Holder: Holds the eyepiece in place. On refractor models, also holds the 90°
diagonal prism in place.
ᕣ 90° Diagonal Prism (refractor models only): Holds the eyepiece upright for easy viewing.
Results in an upright, but reversed viewing of land objects.
ᕤ Eyepiece Holder Thumbscrew: Tightens the eyepiece in place. Tighten to a firm feel only.
ᕥ Eyepiece: Place the supplied eyepiece into the eyepiece holder (reflector models only) or
the 90° Diagonal Prism (refractor models only, 3, Fig. 1) and tighten in place with
thumbscrew (4, Fig.1).
ᕦ Focus Lock Knob: Designed to prevent the focuser drawtube from moving when a heavy
accessory, such as a camera, is attached to the focuser assembly. For normal observing
with an eyepiece and diagonal prism, it is not necessary to use the lock knob.
ᕧ
Red Dot Viewfinder and Mounting Bracket: Provides an easier way to initially sight objects
than the main telescope eyepiece which has a narrower field of view. Slide the switch on the
side of the red dot viewfinder to turn on the device and to change the intensity of the red
dot.
ᕨ Red Dot Viewfinder Alignment Screws: Adjust these screws to align the viewfinder. See
page 12 for more information.
ᕩ Compass/Bubble Level: Compass will assist you in finding North. Bubble level can be
used to level the optical tube when setting the Home Position (included with refractng
models only.)
µ Altitude Setting Circle and Lock
A) Altitude Setting Circle: Displays Altitude (vertical) coordinates (E, Fig. Ib).
B) Altitude Lock: Controls the manual vertical movement of the telescope. Turning
the Altitude lock counterclockwise unlocks the telescope enabling it to be freely
tilted by hand on the vertical axis. Turning the Altitude lock clockwise (to a firm
feel only) prevents the telescope from being moved manually and engages the
vertical motor drive clutch for Audiostar operation (F, Fig. Ib).
¸ Dew Shield: Reduces dew formation on the telescope's primary lens (refractor models only).
¹ Dust Cap: Pull to remove the dust cap from the front lens of the telescope.
Note: The dust cap should be replaced and the power turned off to the telescope
after each observing session. Verify that any dew that might have collected during
the observing session has evaporated before replacing the dust cap.
Ƹ Optical Tube: The main optical component that gathers the light from distant objects and
brings this light to a focus for observation with the eyepiece.
ƹ Cradle Ring Lock Knob: Tighten to a firm feel to hold the optical tube securely in place.
ƺ Cradle Ring: Holds optical tube in place. Attaches to the mounting arm shaft (16, Fig. 1).
ƻ Mounting Arm and Shaft: Holds the optical tube assembly. Attaches to the tripod base
(23, Fig. 1).
Ƽ Computer Control Panel (Fig. Ic)
A. Handbox (HBX) Port: Plug the Audiostar handbox.
B. LED: The red power indicator light illuminates when power is supplied to the
connected handbox and to the telescope’s motor drive.
C. ON Switch: Press to turn the Computer Control Panel and Audiostar ON or OFF.
Note: Always remove the batteries if they are not to be used for a long period of
time.

GETTING STARTED
Packing List
Getting the telescope ready for first observations requires only a few minutes. When first
opening the packing box, note carefully the parts listed on your giftbox.
How to Assemble Your Telescope
The telescope attaches directly to the tripod. The telescope in this way is mounted in an
“Altazimuth” (“Altitude-Azimuth,” or “vertical-horizontal”) format. The telescope in this configuration
moves up and down and from side to side.
1. Open the tripod: After removing the field tripod from its shipping carton, stand the tripod
vertically, with the tripod feet down and with the tripod still fully collapsed. Gently pull the
legs apart to a fully open position.
Fig. 6: Attach cradle to
mounting arm.
2. Attach the tray to the tripod: Place the tray (19, Fig. 1) over the inner support strut that
contains two bolt holes. Line up the bolt holes on the tray with the bolt holes on the strut.
Slide the two included bolts through the top of bolt holes (18, Fig. 1) and tighten the bolts
with the included wing nuts on the bottom side of the tray (Fig. 3).Tighten to a firm feel only.
Note: The tray does not have to be removed when you collapse the tripod at the end
of a viewing session.
3. Three Pads: There are three pads in the tripod base (23, Fig. 1) and three pads on the
mounting arm assembly (16, Fig. 1). These pads allow the mounting arm assembly to move
more easily inside the base. See Fig. 4. This is pointed out just for the user's knowledge of
the telescope; the user does not need to adjust the pads which are pre-installed.
4. Attach the mounting arm assembly to the tripod base: Place the mounting arm
assembly into the tripod base and continue to hold onto the arm assembly. With your other
hand, reach underneath the base and thread the mounting lock knob (26, Fig. 1) through
the tripod base and into the mounting arm assembly. Tighten to a firm feel only; do not
overtighten. While observing, you may wish to loosen this knob and rotate the mounting
arm assembly and optical tube on the horizontal axis.
Fig. 7: Attach and balance
the optical tube.
5. Remove the optical tube assembly from the cradle rings: The optical tube assembly is
shipped with the cradle rings attached. The rings need to be removed before they can be
attached to the mounting arm. Loosen the cradle lock knob (14, Fig. 1) until you can open
the cradle rings. Remove the optical tube assembly (13, Fig. 1) from the cradle rings.
6. Remove 4 screws from the mounting arm shaft: Locate the four screws on the mounting
shaft. Remove the screws using a "+" (Phillips head) screwdriver. Set the screws aside.
7. Attach the cradle to the mounting arm: Line up the cradle with the mounting arm shaft.
The cradle contains a molded "key" that fits into a slot on the shaft. Line up the key and the
slot, and slide the cradle onto the shaft. This automatically lines up the mating threads on
the cradle with the ones on the shaft. Replace the four screws into the mating threads using
the Phillips head screwdriver (Fig. 6). The key and slot on the shaft set limit stops for the
telescope so that it doesn't strike the base or pass beyond approximately 90° upright when
you use the Audiostar handbox.

Because the main telescope has a fairly narrow field of view, locating objects directly in the
main telescope can sometimes be difficult. The red dot viewfinder (Fig. 13) projects a small red
dot that permits you to more easily locate objects. When the red dot viewfinder and optical tube
are aligned to each other, both point to the same position in the sky. An object located in the
viewfinder is therefore in the eyepiece of the main telescope.
Aligning the Red Dot Viewfinder:
It is recommended that you perform steps 1 through 4 of this procedure during the daytime and
step 5 at night.

Choosing an Eyepiece
Intensity Slider
A telescope’s eyepiece magnifies the light gathered by the optical tube. Each eyepiece has a
focal length, expressed in millimetres, or “mm.” The smaller the focal length, the higher the
magnification. For example, an eyepiece with a focal length of 9 mm has a higher magnification
than an eyepiece with a focal length of 25 mm.
Your telescope comes supplied with a low-powered 25 mm or 26 mm eyepiece which gives a
wide, comfortable field of view with high image resolution. Always begin your observations with
this eyepiece.

switching to a higher power eyepiece to enlarge the image.
intensity for the red dot.
NOTE: Viewing conditions vary nightly and depend on the site. Turbulence in the air,
even on an apparently clear night, can distort images. If an image appears fuzzy and
ill-defined, return to a lower power eyepiece for a more well-resolved image.
The power, or magnification of a telescope is determined by the focal length of the telescope
and the focal length of the eyepiece being used. To calculate eyepiece power, divide the
telescope's focal length by the eyepiece's focal length. For example, you may wish to use a
25 mm eyepiece with the StarNavigator102. Look up the focal length of the StarNavigator102
under SPECIFICATIONS: StarNavigator102, page 36. The focal length is listed as 800 mm.

or near the Sun at any
time! Observing the
Sun, even for the
smallest fraction of a
second, will result in
instant and irreversible
eye damage, as well as
physical damage to
the telescope itself.
The eyepiece power, or magnification is
therefore 32X (approximately).
Too Much Power?
Can you ever have too much power? If you’re
referring to eyepiece power (magnification),
yes, you can! The most common beginner’s
mistake is to “overpower” a telescope by using
too high of
a
magnification, which the
telescope’s aperture and atmospheric
conditions cannot reasonably support. Keep
in mind that a smaller, but bright and well-
resolved image is far superior to one that is
larger, but dim and poorly resolved (see
below). Powers above 200X should be
employed only under the steadiest
atmospheric conditions.
Audiostar can calculate the best eyepiece for
you to use.Try out the “Eyepiece Calc” feature
in the Utilities menu.
Most observers should have three or four
additional eyepieces to achieve the full range
of reasonable magnifications possible with the
StarNavigator telescopes. See “OPTIONAL
ACCESSORIES,” page 32.

5. Once you get a feel for how your telescope moves and focuses, try to view something more
challenging, like a bird or a distant moving train.
You can also observe stars and objects in the night sky using this method, but note that objects
begin to slowly drift across the eyepiece field.This motion is caused by the rotation of the Earth.
As you become familiar with the Audiostar handbox operation, you can counteract the drift
using the automatic tracking feature in the Audiostar Setup menu (see TO TRACK AN OBJECT
AUTOMATICALLY, page 16), or by using Audiostar's GO TO capabilities (see GO TO SATURN,
page 19).

Terrestrial Observing
StarNavigator refracting telescopes are excellent high-resolution, terrestrial (land) telescopes
(reflecting telescopes are designed primarily for astronomical observations). Viewing terrestrial
objects requires looking along the Earth's surface through heat waves. These heat waves often
cause degradation of image quality. Lower power eyepieces, such as a 25 mm eyepiece,
magnify these heat waves less than higher power eyepieces.Therefore, lower power eyepieces
provide a steadier, higher quality image. If the image is fuzzy or ill-defined, reduce to a lower
power eyepiece, where the heat waves do not have such an effect on image quality. Observing
in early morning hours, before the ground has built up internal heat, produces better viewing
conditions than during late afternoon hours.

are no other audio files for that object, the audio will stop playing.
Observe the Moon
Point your telescope at the Moon (note that the Moon is not visible every night) and practice
using the Arrow keys and the slew speeds to view different features. The Moon contains many
interesting features, including craters, mountain ranges, and fault lines. The best time to view
the Moon is during its crescent or half phase. Sunlight strikes the Moon at an angle during these
periods and adds a depth to the view. No shadows are seen during a full Moon, causing the
overly bright surface to appear flat and rather uninteresting.
Consider the use of a neutral density Moon filter when observing the Moon. Not only does it cut
down the Moon's bright glare, but it also enhances contrast, providing a more dramatic image.
Astronomical Observing
Used as an astronomical instrument, your telescope has many optical and electromechanical
capabilities. It is in astronomical applications where the high level of optical performance is
readily visible.

To Track an Object Automatically
As the Earth rotates beneath the night sky, the stars appear to move from East to West. The
speed at which the stars move is called the sidereal rate.You can setup your telescope to move
at the sidereal rate so that it automatically "tracks" the stars and other objects in the night sky.
In other words, if the telescope is not tracking an astronomical object, the object will drift out of
the eyepiece field of view. The tracking function automatically keeps an object more or less
centred in the telescope’s eyepiece.

Fig. 16: Alt/Az Home Position.
5. Loosen the horizontal lock (26, Fig. 1) and move the tube until it points to True North.
Note: Irregularities in the earth’s magnetic field results in the direction of True North and
Magnetic North differing and will vary from location to location.
To find True North, use the bubble level/compass and point the telescope tube towards
Magnetic North. Then refer to figure 31 on page 38, which directs you to the North Star
(Polaris). Looking towards Magnetic North locate the Big Dipper; follow the two stars in the
bowl of the Big Dipper, as shown in Figure 31, to the North Star. With the tube still level,
rotate it so that it points towards the North Star. The tube is now pointing True North.

The fastest and easiest way to locate objects with Audiostar's GO TO capabilities is to use Easy
Align.
Audiostar automatically picks two stars from its database for the Easy Align procedure. During
this procedure, Audiostar slews the telescope to a first alignment star. The user is asked to
verify that the telescope is pointed at the chosen star and then prompted to centre the star in
the eyepiece. The process is repeated with a second star to complete the alignment.
NOTE: Before aligning the telescope, first verify that INITIALIZING AUDIOSTAR,

How to Easy Align Your Telescope
If you have performed Initializing AudioStar as shown on page 16, continue to step 2.
Otherwise, before proceeding, please perform the steps shown on page 16, Initalizing
AudioStar.
NOTE: For the Easy Align procedure to function properly, AudioStar must have the
correct time, date and location of the observing site. If you have changed locations
since your telescope was last used, or would like to change this information, see
the Setup Menu on page 25 for more information.
1. Option Screen - AudioStar displays "Press 0 to Align or MODE fro Menu.” Press "0" to
begin the Easy Align procedure.
2. North Method -"North Method: 1=True 2=Compass" displays. Press the 1 key if you will be
placing the telescope in the True North Home Position. Press the 2 key if you will be placing
the telescope in the Magnetic North Home Position. See page 16 for more information on
setting the telescope into the Home Position.
3. Set Alt/Az Home Position - Audiostar then prompts you to set the telescope in the Alt/Az
Alignment home position. See SET ALT/AZ HOME POSITION, page 16.
4
Star Alignment - Audiostar then chooses two stars to align upon. When the telescope
slews to the first star for alignment, it may not appear in the field of view in the eyepiece.
The alignment star should be easily recognized and be the brightest star in the area of the
sky where the telescope is pointing. Use the Arrow keys to move the telescope until the
star is visible and centred in the eyepiece. Press ENTER. Repeat procedure for the second
alignment star.
When the procedure is performed correctly, "Alignment Successful" displays. If Audiostar
does not display this message, perform this procedure again.
NOTE: Audiostar locates alignment stars based on the date, time, and location
entered. The alignment stars may change from night to night. All that is required is
for the observer to centre the selected stars in the eyepiece when prompted.
NOTE: The GO TO key also allows you to perform a "spiral search." A spiral search
is useful when the telescope slews to an object, but that object is not visible in the
eyepiece after the telescope finishes its search. (This sometimes occurs during an
alignment procedure.) Press GO TO when the slew is finished and the telescope
starts slewing in a spiral pattern at a very slow speed around the search area. Look
through the eyepiece and when the
object does become visible, press
MODE to stop the spiral search.
Then use the Arrow keys to centre
the object.
Which One’s the
Alignment Star?
If Audiostar has chosen an alignment star
with which you are unfamiliar, how can you be
sure if the star in your eyepiece is really the
alignment star?
Two other methods of alignment are
available to the observer: Two-Star and
One-Star. These methods are included in
case the observer prefers to pick out his or
her own alignment stars.
The rule of thumb is that an alignment star is
usually the brightest star in that area of the
sky. When you view an alignment star in an
eyepiece, it stands out dramatically from the
rest of the stars in that portion of the sky.
Two-Star Alt/Az Alignment
Two-Star Alignment requires some
knowledge of the night sky. Two-Star
Alignment is identical to Easy: Align (see

which you are familiar from this database when first trying out this method or the One-Star
Alignment method.
One-Star Alt/Az Alignment
One-Star Alignment also requires some knowledge of the night sky. One-Star Alignment is
identical to Easy: Align (see EASY (TWO-STAR) ALIGN, Pg. 17), except Audiostar displays a
database of bright stars and one star is chosen by the observer from this database for
alignment.
IMPORTANT NOTE: The accuracy of One-Star Alt/Az Alignment, unlike the Two-
Star Alignment procedures, depends on how well the observer levels the telescope
and how close to North the telescope is pointed when setting the Home Position
(Fig. 16). Because the Two-Star Alignment methods use two stars to align upon,
they are more precise than One-Star Alignment.
Go To Saturn
After performing the Easy Align procedure, the motor drive begins operating and the telescope
is aligned for a night of viewing. Objects in the eyepiece should maintain their position even
though the Earth is rotating beneath the stars.
IMPORTANT NOTE: Once aligned, only use GO TO or the Arrow keys to move the
telescope. Do not loosen the telescope locks (10F, Fig. 1b and 26, Fig. 1), or move
the base manually, or alignment will be lost.
This exercise shows how to select a object (Saturn) for viewing from Audiostar’s database.
NOTE: Saturn is not visible all the time and you may need to choose another object
from Audiostar's Object database; however, the procedure, as described below,
remains the same; just choose a different object in step #3.

selected object. On the AudioStar display "Saturn" displays and a set of coordinates
displays. Note that Saturn's (and other planets) coordinates change throught the year.
5. Press GO TO. “Saturn: Slewing...” displays and the telescope slews until it finds Saturn.You
may need to use the Arrow keys to centre Saturn precisely in the eyepiece. Audiostar then
automatically moves the telescope so that it "tracks" Saturn (or whatever other object you
may have chosen); i.e., Saturn remains centred in the eyepiece.

MENUS AND MENU OPTIONS
Object Menu
Almost all observing with Audiostar is performed using the Object menu category. (NOTE:
Exceptions include Guided Tour and Landmark Survey. See GO TO SATURN, page 19, for an
)
example of observing using the Object menu. Also see TAKE A GUIDED TOUR, page 19.
Many Audiostar menu categories contain databases. An Audiostar database is a list of viewable
objects, such as stars, planets, comets, nebulae and so forth. When one of these objects is
selected from a database, Audiostar moves your telescope (if properly aligned) and points it at
the selected object.
The Object Menu options include:
Solar System is a database of the eight planets (Earth is not included) in order out from the
Sun, followed by the Moon, asteroids, and comets.
Constellation is a database of all 88 Northern and Southern Hemisphere constellations. When
this menu option is chosen and a constellation name appears on the first line of the screen,
press GO TO once to change the second line to the name of the brightest star in the
constellation. Press GO TO a second time to slew the telescope to that star. Use the Scroll keys
to cycle through the list of stars in the constellation, from brightest to dimmest.
Deep Sky is a database of objects outside our Solar System such as nebulae, star clusters,
galaxies, and quasars.
Star is a database of stars listed in different categories such as named, double, variable, or
nearby.
Satellite is a database of Earth-orbiting objects such as the International Space Station, the
Hubble Space Telescope, Global Positioning System (GPS) satellites, and geosynchronous
orbit satellites.
User Objects allows the user to define and store in memory deep-sky objects of specific
interest that are not currently in the Audiostar database. See APPENDIX B for more information.

Observing Considerations
•
•
Try to pick an observing site away from
street and house lights, and car
headlights. While this is not always
possible, the darker the site, the better.
ܖ Set: Enter the time of day for the alarm to
sound, in hours, minutes, and seconds,
then press ENTER.
Give your eyes about ten minutes to
adjust to the darkness before observing.
Give your eyes a rest from observing
every ten or fifteen minutes to relieve
eyestrain.
ܖ Start/Stop: Activates the alarm set
previously. Use the Scroll keys to toggle
between ON and OFF. When ON is
displayed, press ENTER to activate the
alarm. When the alarm time arrives,
Audiostar beeps. Press ENTER to
deactivate the alarm.
•
Try not to use a standard flashlight.
Seasoned observers use red LED
flashlights or tape red cellophane over
their flashlights for setup and map reading
so they don’t have to continually readjust
their eyes to the darkness. Be careful not
to shine bright lights if there are other
observers in the area. Never shine a
flashlight into a telescope while someone
is observing!
Eyepiece Calc calculates information about
an eyepiece for the specific telescope to
which Audiostar is connected.
ܖ Field of View: Scroll through a list of
available eyepieces. When an eyepiece
is selected, the field of view is
calculated.
•
•
•
Dress warmly. It gets chilly when you’re
sitting for prolonged periods, even on
some summer nights.
Practice setting up your equipment during
the day or in a lighted area to become
familiar with it before going to a dark site.
ܖ ܖ Magnification: Scroll through a list of
available eyepieces. When an eyepiece is
selected, the magnification is calculated.
Use your 25 mm eyepiece to view
terrestrial objects and wider areas of
space, such as open star clusters. Use
your higher power eyepieces when you
wish to view something up close, such as
craters on the Moon or the rings of Saturn.
Suggest: Audiostar calculates and
suggests the best eyepiece for viewing,
based on the telescope and the object
being viewed.
•
Know your observing site. If you’re going
to try out an unfamiliar site, check it out in
the daylight for obstructions and pitfalls.
Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun.
Do not look through the telescope as it is moving.

forgetting its alignment. With "Sleep Scope" selected, press ENTER to activate the Sleep
function. Audiostar goes dark, but the internal clock keeps running. Press any key, except
ENTER, to re-activate Audiostar and the telescope.
Park Scope is designed for a telescope that is not moved between observing sessions. Align
the telescope one time, then use this function to park the telescope. Next time it is powered up,
enter the correct date and time – no alignment is required. Pressing ENTER causes the
telescope to move to its pre-determined Park position. Once parked, the screen prompts to turn
off power.
IMPORTANT NOTE: When the "Park Scope" option is chosen and the display
prompts you to turn off the telescope's power, Audiostar is unable to be returned to
operation without turning the power off and then back on.
Language: Select the English language or other pre-loaded language and AudioStar will display
text and audio descriptions in the selected language.
Audio clip: Select from Automatic or On Demand. The Automatic settng will automatically play
the object audio when a night sky object is selected on the AudioStar. The On Demand feature
requires the user to press the ? key once a night sky object is selected. Pressing the ? key will
then play the audio presentations for the selected object.
Cord Wrap, when set to "On," moves the telescope in such a way as to prevent the cords and
cables attached to your telescope assembly from getting wound around the assembly and
tangled as the telescope slews to objects. "Off" is the default setting.
Setup Menu
The Setup menu’s primary function is to align the telescope (see EASY ALIGN, page 17).
However, there are numerous other features available within the Setup menu, including:
Date changes the date used by Audiostar. This function is useful to check events in the past or
future. For example, set the Date menu for a day three months in the future. Then check the
"Select Item: Event" menu for the Sunset time on that date. See EVENT MENU, page 23.
Note: The time and
date information is
kept by a high
precision internal
clock, which is set at
the factory and held
by a long-life lithium
battery.
Time changes the time entered into Audiostar. Setting the correct time is critical for Audiostar
to properly calculate locations and events. Time may be set to 24-hour mode (military time) by
selecting the "blank" option which follows the "AM" and "PM" options.
Daylight Saving is used to enable or disable Daylight Savings time.
Replace the internal
clock’s battery with a

value near 100, the telescope tube responds more quickly (it responds immediately at
100%) as you hold down an Arrow key and also slews (moves) the tube more quickly. If you
enter a value near 0, it takes longer for the tube to respond as you hold down an Arrow key
and also slews the tube more slowly. Experiment with this option. Try changing the
percent value until you get a "feel" for the Arrow keys that is comfortable for you.
ܖ ܖ Alt Percent: The Alt (Altitude) Percent operates identical to the Az Percent option (see
above), but allows you to change the altitude backlash, i.e., the way the Arrow keys move
the telescope when moving along the altitude (vertical) axis.
Train Drive: Trains the Altitude and Azimuth motors to locate objects with more precision.
If you are experiencing any problems with pointing accuracy, follow the procedure
described in APPENDIX D: TRAINING THE DRIVE, page 41, to insure accurate pointing and
tracking.
ܖ Tracking Rate: Changes the speed at which the telescope tracks targets in the sky.
a. Sidereal: The default setting for Audiostar; sidereal rate is the standard rate at which
stars move from East to West across the sky due to the rotation of the Earth.
b. Lunar: Choose this option to properly track the Moon over long observing sessions.
c. Custom: Allows entry of user-defined tracking rates.
ܖ ܖ ܖ Reverse L/R: Reverses the functions of the Left and Right Arrow keys (i.e., the Right key
moves the telescope to the left).
Reverse UP/DOWN: Reverses the functions of the Up and Down Arrow keys (i.e., the Up
key moves the telescope down).
Calibrate Motor: If the telescope motors appear to have a problem, use this option to
retest the motors before performing a Reset. This option is also used if an Audiostar unit is
moved between telescopes, to match Audiostar to the new telescope. To calibrate the
motors, select this option and press ENTER.
ܖ High Precision: If High Precision is turned on, when looking for a faint celestial object (i.e.,
a nebula or galaxy), Audiostar first slews to a nearby bright star and displays "ENTER to
Sync." Centre the star in the eyepiece, then press ENTER. At that point the telescope has
a high precision alignment to that part of the sky and it then slews to the object that was
originally requested.
Targets switches between Astronomical targets and Terrestrial targets. If "Astronomical" is
selected, the telescope tracking motor is activated and any object you observe will remain
centred in the eyepiece. If "Terrestrial" is selected, the tracking motor is turned off. To learn how
to track an object automatically, see page 16.

allows you to check on how much memory is still available.
1. Navigate to the "Setup: Statistics" menu option and press ENTER.
2. "Statistics: 97.6K Char. Free" displays. This is the amount of memory that is still available
to the user.
Identify
This procedure allows you to use Audiostar to identify objects you have found in the night sky
using the Arrow keys. If the object is not in Audiostar's database, Audiostar displays information
about an object in its database that is closest to the one you queried about.
IMPORTANT NOTE: For this function to operate properly, you must first set the
telescope in the home position and initialize Audiostar. If you physically move the
telescope after initialization, this function will fail to operate properly.
In this procedure, you will centre an object you wish to have identified by Audiostar in the
telescope eyepiece and use the "Identify" menu to find out information about the object or the
nearest object to it in the Audiostar database.
1. Centre the object you wish to have identified in the telescope's eyepiece.

Look into the Future
The Audiostar Date menu option in the Setup menu is much more than just an entry
of today's date; with it you can look far into the future or learn about past events.
Audiostar can calculate the date and times of future events and, except for eclipses,
past events as well (based on the current calendar system). E.g., a Sunrise on
March 6, 2043 A.D. or the Vernal Equinox in 1776 A.D.To use this feature, enter the
desired date in the Setup menu and select an option in the Event menu.
Audiostar can calculate dates and times for Sunrises, Sunsets, Moonrises,
Moonsets, Moonphases, Solar and Lunar Eclipses (for the next 100 years), meteor
showers, equinoxes and solstices, and the minimums of Algol.
One very practical use of the date menu is to check the Sunset option to determine
when you can begin your astronomical observing.

OPTIONAL ACCESSORIES
A wide assortment of professional Meade accessories is available for the StarNavigator
telescopes. The premium quality of these accessories is well suited to the quality of the
instrument itself. Consult meade.com for complete details on these and other
accessories.
Eyepieces: For higher and lower magnifications, Meade Series 4000 Super Plössl (SP) yield
high-resolution imaging with all StarNavigator telescope models. A useful selection includes the
SP 15 mm and SP 12.4 mm eyepieces.
#126 2x Barlow Lens (1.25"/3 cm): Doubles each eyepiece power while maintaining excellent
image corrections. For example, a 9 mm eyepiece used with the StarNavigator114 yields a
power of 111X; when used in conjunction with the #126 Barlow lens, the same eyepiece yields
222X.
#928 45° Erecting Prism: The 90° diagonal provided with StarNavigator refractors results in
upright-but-reversed viewing of land subjects.The #928 45° Erecting Prism (1.25"/3 cm) orients
the image correctly in terrestrial applications and results in a comfortable 45° viewing angle. For
use with refractors only.
Camera Adapter: StarNavigator telescopes may be used for through-the-telescope
photography of the Moon and planets or for terrestrial objects. For eyepiece-projection
photography with any of these telescopes, use the Basic Camera Adapter (1.25"/3 cm).
#505 AstroFinder™ Software and Cable Connector Kit: Displays more than 15,000 celestial
wonders – galaxies, nebulae, star clusters, stars, and planets – on your PC, enabling even the
beginner to locate and identify objects to observe with the telescope or to print out star charts
for use in observing sessions. Operates with any Windows™-based personal computer. The
Cable Connector Kit permits connection of any StarNavigator telescope model, Audiostar, and
PC, for downloading of new software to Audiostar or for updating of Earth satellite or other
celestial object positions. This kit is included with each AstroFinder Software package.

CARING FOR YOUR TELESCOPE
Your StarNavigator telescope is a precision optical instrument designed to yield a lifetime of
rewarding observations. Given the care and respect due any precision instrument, your
telescope will rarely, if ever, require factory servicing. Maintenance guidelines include:
a. Avoid cleaning the telescope’s optics: a little dust on the front surface of the telescope’s
correcting lens causes virtually no degradation of image quality and should not be
considered reason to clean the lens.
b. When absolutely necessary, dust on the front lens should be removed with gentle strokes
of a camel hair brush or blown off with an ear syringe (available at any pharmacy). DO
NOT use a commercial photographic lens cleaner.
c. Organic materials (e.g., fingerprints) on the front lens may be removed with a solution of
3 parts distilled water to 1 part isopropyl alcohol.You may also add 1 drop of biodegradable
dishwashing soap per pint of solution. Use soft, white facial tissues and make short, gentle
strokes. Change tissues often.
CAUTION: Do not use scented or lotioned tissues or damage could result to the
optics.
d. If used outdoors on a humid night, water condensation on the telescope surfaces will
probably result. While such condensation does not normally cause any damage to the
telescope, it is recommended that the entire telescope be wiped down with a dry cloth
before the telescope is packed away. Do not, however, wipe any of the optical surfaces.
Rather, simply allow the telescope to sit for some time in the warm indoor air, so that the
wet optical surfaces can dry unattended.
e. If your telescope is not to be used for an extended period, perhaps for one month or more,
it is advisable to remove the batteries from the telescope. Batteries left in the telescope for
prolonged periods may leak, causing damage to the telescope’s electronic circuitry.
f. Do not leave the telescope inside a sealed car on a warm summer day; excessive ambient
temperatures can damage the telescope’s internal lubrication and electronic circuitry.
Collimation
StarNavigator refracting telescopes are optically aligned (collimated) at the factory prior to
shipment, and it is never necessary to re-collimate the optics of these models. Meade
StarNavigator114 and StarNavigator130 reflecting telescope models are also factory-aligned,
but may occasionally require re-alignment, particularly if the telescope has received rough
handling in shipment. Before using one of these models for the first time, check the alignment
of the optics as outlined in this section. Good optical alignment is essential for telescope
performance, and in any case the alignment procedure is not difficult to follow.
The optical systems of Meade StarNavigator reflecting telescopes include the following parts:
primary mirror (1, Fig. 23); secondary mirror (2, Fig. 23); secondary mirror-holder (3, Fig. 23);
secondary mirror-vanes (4, Fig. 23) and (1, Fig. 24); primary mirror-tilt screws (5, Fig. 23). The
telescope’s image is brought to a focus at (6, Fig. 23).
1. Confirm alignment - To confirm optical alignment look down the focuser drawtube (1, Fig.
26) with the eyepiece removed. The edge of the focuser drawtube frames reflections of the
primary mirror (2, Fig. 26), the secondary mirror (3, Fig. 26), the three (“spider”) vanes (4,
Fig. 26) holding the secondary mirror, and the observer’s eye (5, Fig. 26). With the optics
properly aligned, all of these reflections appear concentric (centred), as shown in Fig. 26.
Any deviation from concentricity of any of these telescope parts with the eye requires
adjustments to the secondary mirror-holder (Fig. 24) and/or the primary mirror cell (Fig.
25,) as described below.
2. Secondary mirror-vane adjustments: If the secondary mirror (1, Fig. 27) is left or right of
centre within the drawtube (2, Fig. 27), slightly loosen the 3-vane adjustment/lock knobs (1, Fig.
24) located on the outside surface of the main tube and slide the entire secondary mirror-holder
system up or down in the slotted holes of the main tube until the secondary mirror is centred in
the drawtube. If the secondary mirror (1, Fig. 27) is above or below centre within the drawtube,
Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun.
Do not look through the telescope as it is moving.

thread inward one of the adjustment/lock knobs (1, Fig. 24) while unthreading another of these
knobs. Only make adjustments to two knobs at a time until the secondary mirror appears as in
Fig. 28.
3. Secondary mirror-holder adjustments: If the secondary mirror (1, Fig. 28) is centred in the
focuser drawtube (2, Fig. 28), but the primary mirror is only partially visible in the reflection (3,
Fig. 28), the three “+” (Phillips head) secondary mirror-tilt screws (2, Fig. 24) should be slightly
unthreaded to the point where the secondary mirror-holder (3, Fig. 24) can rotate about its axis
parallel to the main tube. Grasp the secondary mirror-holder (avoid touching the mirror surface!)
with your hand and rotate it until, looking through the drawtube, you can see the primary mirror
centred as well as possible in the reflection of the secondary mirror. With the rotation of the
secondary mirror-holder at this best-possible position, thread in the three Phillips head screws
(2, Fig. 24) to lock the rotational position. Then, if necessary, make adjustments to these three
Phillips head screws to refine the tilt-angle of the secondary mirror, until the entire primary
mirror can be seen centred within the secondary mirror’s reflection. With the secondary mirror
thus aligned the image through the drawtube appears as in Fig. 29.
4. Primary mirror adjustments: If the secondary mirror (1, Fig. 29) and the reflection of the
primary mirror (2, Fig. 29) appear centred within the drawtube (3, Fig. 29), but the reflection of
your eye and the reflection of the secondary mirror (4, Fig. 29) appear off-centre, then the
primary mirror tilt requires adjusting, using the Phillips head screws of the primary mirror cell
(3, Fig. 25). These primary mirror-tilt screws are located behind the primary mirror, at the lower
end of the main tube. See Fig. 25. Before adjusting the primary mirror-tilt screws, first unscrew
by several turns (use either a hex wrench or pliers) the three hex-head primary mirror lock
screws (2, Fig. 25) which are also located on the rear surface of the primary mirror cell and
which alternate around the cell’s circumference with the three Phillips head screws. Then by
trial and error turn the primary mirror Phillips head tilt screws (3, Fig. 25) until you develop a
feel for which way to turn each screw to centre the reflection of your eye in the drawtube. (An
assistant is helpful in this operation.) With your eye centred as shown in Fig. 26, turn the three
hex head primary mirror lock screws (2, Fig. 25) to re-lock the tilt-angle of the primary mirror.
The telescope’s optical system is now aligned, or collimated. This collimation should be re-
checked from time to time, with small adjustments (per steps 1, 2, and/or 3, above) effected as
required to keep the optics well-aligned.
Meade Consumer Solutions
If you have a question concerning your StarNavigator telescope, contact the Meade
Instruments Consumer Solutions Department at:
Telephone: 800-626-3233

APPENDIX A
Celestial Coordinates
It is helpful to understand how to locate celestial
objects as they move across the sky.

+90 Dec.
Star
A celestial coordinate system was created that
maps an imaginary sphere surrounding the Earth
upon which all stars appear to be placed. This
mapping system is similar to the system of latitude
and longitude on Earth surface maps.

Right Ascension
In mapping the surface of the Earth, lines of
longitude are drawn between the North and South
Poles, and lines of latitude are drawn in an East-
West direction, parallel to the Earth’s equator.
Similarly, imaginary lines have been drawn to form
a latitude and longitude grid on the celestial
sphere. These lines are known as Right
Ascension and Declination.

Fig. 30: Celestial Sphere.
The celestial map also contains two poles and an equator just like a map of the Earth. The
poles of this coordinate system are defined as those two points where the Earth’s north and
south poles (i.e., the Earth's axis), if extended to infinity, would cross the celestial sphere.Thus,
the North Celestial Pole (1, Fig. 30) is that point in the sky where an extension of the North Pole
intersects the celestial sphere. This point in the sky is located very near the North Star, Polaris.
The celestial equator (2, Fig. 30) is a projection of the Earth’s equator onto the celestial sphere.
So just as an object's position on the Earth’s surface can be located by its latitude and
longitude, celestial objects may also be located using Right Ascension and Declination. For
example, you could locate Los Angeles, California, by its latitude (+34°) and longitude (118°).
Similarly, you could locate the constellation Ursa Major (the Big Dipper) by its Right Ascension
(11hr) and its Declination (+50°).
• Right Ascension (R.A.): This celestial version of longitude is measured in units of hours (hr),
minutes (min) and seconds (sec) on a 24-hour "clock" (similar to how Earth's time zones are
determined by longitude lines). The "zero" line was arbitrarily chosen to pass through the
constellation Pegasus — a sort of cosmic Greenwich meridian. R.A. coordinates range from
0hr 0min 0sec to 23hr 59min 59sec. There are 24 primary lines of R.A., located at 15-degree
intervals along the celestial equator. Objects located further and further East of the zero R.A.
grid line (0hr 0min 0sec) carry higher R.A. coordinates.
• Declination (Altitude): This celestial version of latitude is measured in degrees, minutes,
and seconds (e.g., 15° 27' 33"). Dec. locations north of the celestial equator are indicated with
a plus (+) sign (e.g., the Dec. of the North celestial pole is +90°). Dec. locations south of the
celestial equator are indicated with a minus (–) sign (e.g., the Dec. of the South celestial pole
is –90°). Any point on the celestial equator (such as the the constellations of Orion, Virgo, and
Aquarius) is said to have a Declination of zero, shown as 0° 0' 0."
Locating the Celestial Pole
To get basic bearings at an observing location, take note of where the Sun rises (East) and sets
(West) each day. After the site is dark, face North by pointing your left shoulder toward where
the Sun set. To precisely point at the pole, find the North Star (Polaris) by using the Big Dipper
as a guide (Fig. 31).
IMPORTANT NOTE: For almost all
astronomical observing requirements,
approximate settings are acceptable. Do
not allow undue attention to precise
alignment of the telescope to interfere with
your basic enjoyment of the instrument.

APPENDIX B
TIP:
Using Audiostar to Find Objects Not in the Database
Entering R.A. and
Dec. Coordinates of
an object without
using the menus:
If you do not wish to
navigate through the
menus, a more direct
way to enter
coordinates is to press
and hold MODE for
two seconds or more.
R.A. and Dec.
Although Audiostar contains a database of more than 32,000 celestial objects (stars, nebulae,
planets, etc.) that you can observe, you may eventually want to view objects that are not part of
the database. Audiostar provides a feature that allows you to enter an object's R.A and Dec.
coordinates in the "User: Objects" option of the Object menu and allows automatic slewing of
the telescope to the user-entered coordinates.
In order to use this menu option, you first need to look up the R.A and Dec. coordinates of the
object or objects you wish to observe. Check out your local library, computer store, bookstore,
CD Roms, Internet, or magazines (such as Sky & Telescope or Astronomy), to find coordinates
of celestial objects. The objects/coordinates you enter become part of your own permanent
database, called "User Objects."
To enter coordinates of an object into the "User: Objects" option of the Object menu:
coordinates display.
Press GO TO. "Object

APPENDIX C
Observing Satellites
In this procedure, you will prepare your telescope to observe a satellite pass.
1. Go to the "Object: Satellite" menu option and press ENTER.
2. Use the Scroll keys to scroll through the list of satellites.
3. Select a satellite from the list and press ENTER.
4. "Calculating...." and then "Tracking..." displays. If the satellite is going to make a pass,
"Located" displays.
5. Use the Scroll keys to display data about the pass: aos – acquisition of signal and los –
loss of signal. If you subtract the aos from the los, you can calculate how long the satellite
will be visible. Location information also displays.
6. "Alarm" displays after the location information. Press ENTER and Audiostar automatically
sets the alarm to sound a minute before the satellite's scheduled appearance. You may
return to regular observations until the alarm goes off.
7. When the alarm goes off, return to the Satellite menu and press a Scroll key until the
desired satellite is on the top line of the display.
8. Press GO TO. Audiostar slews the telescope to where the satellite should appear. The
motor drive stops and a countdown is displayed.
NOTE: If the scheduled appearance position of the satellite is obstructed (i.e., by a
building, tree, or hill), press ENTER and Audiostar starts to move the telescope
along the expected satellite track. When the track clears the obstruction, press
ENTER again to pause the telescope, then continue with this procedure.
9. With about 20 seconds left on the countdown timer, start watching through the telescope
viewfinder for the satellite to enter the field of view.
10. When the satellite enters the viewfinder field of view, press ENTER. The telescope starts
to track with the satellite.
11. Use the Audiostar Arrow keys to centre the object in the viewfinder, then look through the
eyepiece to view the object.
Satellite orbits change and new satellites (including the Space Shuttle) are launched. Visit the
and instructions on how to download this data to Audiostar. If orbital parameters are more than
one month old, the satellite pass may not happen at the time predicted by Audiostar.
Downloading requires the optional #505 AstroFinder™ Software and Cable Connector Kit. See
OPTIONAL ACCESSORIES, page 32.
NOTE: Satellite observing is an exciting challenge. Most satellites are in low orbit,
travelling at approximately 17,500 mph/28,163 kph.When visible, they move quickly
across the sky and are only in the field of view for a few minutes, requiring Audiostar
to slew the telescope rapidly. Best viewing is near Sunrise or Sunset when the sky
is still dark. Viewing in the middle of the night can be problematic because the
satellite may pass overhead, but not be visible as it is in the Earth's shadow.
Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun.
Do not look through the telescope as it is moving.

BASIC ASTRONOMY
In the early 17th century, the Italian scientist Galileo, using a telescope smaller than your
StarNavigator model, turned it skyward instead of looking at the distant trees and mountains.
What he saw, and what he realized about what he saw, has forever changed the way mankind
thinks about the universe. Imagine what it must have been like being the first human to see
moons revolve around the planet Jupiter or to see the changing phases of Venus! Because of
his observations, Galileo correctly theorized Earth's movement and position around the Sun,
and in doing so, gave birth to modern astronomy.Yet Galileo's telescope was so crude, he could
not clearly make out the rings of Saturn.
Galileo's discoveries laid the foundation for understanding the motion and nature of the planets,
stars, and galaxies. Building on his foundation, Henrietta Leavitt determined how to measure
the distance to stars, Edwin Hubble gave us a glimpse into the possible origin of the universe,
Albert Einstein unraveled the crucial relationship of time and light, and 21st-century
astronomers are currently discovering planets around stars outside our solar system. Almost
daily, using sophisticated successors to Galileo's telescope, such as the Hubble Space
Telescope and the Chandra X-Ray Telescope, more and more mysteries of the universe are
being probed and understood. We are living in the golden age of astronomy.
Unlike other sciences, astronomy welcomes contributions from amateurs. Much of the
knowledge we have on subjects such as comets, meteor showers, variable stars, the Moon, and
our solar system comes from observations made by amateur astronomers. So as you look
through your Meade StarNavigator telescope, keep in mind Galileo.To him, a telescope was not
merely a machine made of glass and metal, but something far more—a window through which
the beating heart of the universe might be observed.
Audiostar Glossary
Be sure to make use of Audiostar’s Glossary feature. The Glossary menu provides an
alphabetical listing of definitions and descriptions of common astronomical terms. Access
directly through the Glossary menu or through hypertext words embedded in Audiostar. See
GLOSSARY MENU, page 24, for more information.
Objects in Space
Listed below are some of the many astronomical objects that can be seen with the
StarNavigator series telescope:
The Moon
The Moon is, on average, a distance of 239,000 miles (380,000 km) from Earth and is best
observed during its crescent or half phase when sunlight strikes the Moon’s surface at an angle.
It casts shadows and adds a sense of depth to the view (Fig. 34). No shadows are seen during
a full Moon, causing the overly bright Moon to appear flat and rather uninteresting through the
telescope. Be sure to use a neutral Moon filter when observing the Moon. Not only does it
protect your eyes from the bright glare of the Moon, but it also helps enhance contrast,
providing a more dramatic image.
Brilliant detail can be observed on the Moon, including hundreds of lunar craters and maria,
described below.
Fig. 34: The Moon.
Note the deep
shadows in the craters.
Craters are round meteor impact sites covering most of the Moon’s surface. With no
atmosphere on the Moon, no weather conditions exist, so the only erosive force is meteor
strikes. Under these conditions, lunar craters can last for millions of years.
Maria (plural for mare) are smooth, dark areas scattered across the lunar surface. These dark
areas are large ancient impact basins that were filled with lava from the interior of the Moon by
the depth and force of a meteor or comet impact.
Twelve Apollo astronauts left their bootprints on the Moon in the late 1960s and early 1970s.
However, no telescope on Earth is able to see these footprints or any other artifacts. In fact, the
smallest lunar features that may be seen with the largest telescope on Earth are about one-half
mile across.
Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun.
Do not look through the telescope as it is moving.

Planets
Planets change positions in the sky as they orbit around the Sun. To locate the planets on a
given day or month, consult a monthly astronomy magazine, such as Sky and Telescope or
Astronomy. You can also consult Audiostar for information about planets. Scroll to the "Object:
Solar System" menu and scroll through the lists of planets. When a planet you are interested
in displays, press ENTER. Use the Scroll keys to display information about the planet, such as
the planet's coordinates, and the rise and set times (Tip: enter a date in the Date menu and
you can determine if a planet will be visible during the night of the entered date by checking its
rise and set times). Listed below are the best planets for viewing through the StarNavigator
series.
Venus is about nine-tenths the diametre of Earth. As Venus orbits the Sun, observers can see
it go through phases (crescent, half, and full) much like those of the Moon. The disk of Venus
appears white as Sunlight is reflected off the thick cloud cover that completely obscures any
surface detail.
Fig. 35: Jupiter and
its four largest
moons. The moons
can be observed in
a different position
every night.
Mars is about half the diametre of Earth, and appears through the telescope as a tiny reddish-
orange disk. It may be possible to see a hint of white at one of the planet’s Polar ice caps.
Approximately every two years, when Mars is closest to Earth in its orbit, additional detail and
colouring on the planet's surface may be visible.
Jupiter is the largest planet in our solar system and is 11 times the diameter of Earth. The
planet appears as a disk with dark lines stretching across the surface. These lines are cloud
bands in the atmosphere. Four of Jupiter’s 16 moons (Io, Europa, Ganymede, and Callisto) can
be seen as “star-like” points of light when using even the lowest magnification (Fig. 35). These
moons orbit Jupiter so that the number of moons visible on any given night changes as they
circle around the giant planet.
Fig. 36: Saturn has
the most extensive
ring structure in our
Solar System.
Saturn is nine times the diameter of Earth and appears as a small, round disk with rings
extending out from either side (Fig. 36). In 1610, Galileo, the first person to observe Saturn
through a telescope, did not understand that what he was seeing were rings. Instead, he
believed that Saturn had “ears.” Saturn’s rings are composed of billions of ice particles ranging
in size from a speck of dust to the size of a house. The major division in Saturn's rings, called
the Cassini Division, is occasionally visible.Titan, the largest of Saturns 18 moons, can also be
seen as a bright, star-like object near the planet.
Deep-Sky Objects
Star charts can be used to locate constellations, individual stars and deep-sky objects.
Examples of various deep-sky objects are given below:
Stars are large gaseous objects that are self-illuminated by nuclear fusion in their core.
Because of their vast distances from our solar system, all stars appear as pinpoints of light,
irrespective of the size of the telescope used.
Fig. 37: The
Pleiades is one of
the most beautiful
open clusters.
Nebulae are vast interstellar clouds of gas and dust where stars are formed. Most impressive
of these is the Great Nebula in Orion (M42), a diffuse nebula that appears as a faint wispy gray
cloud. M42 is 1600 light years from Earth.
Open Clusters are loose groupings of young stars, all recently formed from the same diffuse
nebula. The Pleiades is an open cluster 410 light years away (Fig. 37).
Constellations are large, imaginary patterns of stars believed by ancient civilizations to be the
celestial equivalent of objects, animals, people, or gods. These patterns are too large to be
seen through a telescope.To learn the constellations, start with an easy grouping of stars, such
as the Big Dipper in Ursa Major. Then, use a star chart to explore across the sky.
Galaxies are large assemblies of stars, nebulae, and star clusters that are bound by gravity.
The most common shape is spiral (such as our own Milky Way), but galaxies can also be
elliptical, or even irregular blobs.The Andromeda Galaxy (M31) is the closest spiral-type galaxy
to our own. This galaxy appears fuzzy and cigar-shaped. It is 2.2 million light years away in the
constellation Andromeda, located between the large “W” of Cassiopeia and the great square of
Pegasus.
