Never use a Meade NGCor NG™  
Telescope to look at the Sun! Looking at or  
near the Sun will cause instant and irre-  
versible damage to your eye. Eye damage is  
often painless, so there is no warning to the  
observer that damage has occurred until it is  
too late. Do not point the telescope or its  
viewfinder at or near the Sun. Do not look  
through the telescope or its viewfinder as it is  
moving. Children should always have adult  
supervision while observing.  
CAUTION: Use care to install batteries in the  
orientation indicated by the battery connec-  
tor. Follow battery manufacturer's precau-  
tions. If these precautions are not followed,  
batteries may explode, catch fire, or leak.  
Improperly installed batteries void your  
Meade warranty.

Telescope and Tripod Features  
b Dust Cap (not shown): Pull to remove from the dew shield (17, Fig. 1).  
NOTE: The dust cap should be replaced after each observing session and  
the power turned off (NGC models only) to the telescope. Verify that any  
dew that might have collected during the observing session has evaporat-  
ed prior to replacing the dust cap.  
C Optical Tube: The main optical component that gathers the light from distant  
objects and brings this light to a focus for examination with the eyepiece.  
D Optical Tube Attachment Bracket: Attach the optical tube to this bracket. See  
HOW TO ASSEMBLE YOUR TELESCOPE, page 8, for more information.  
E Control Panel (Fig. 3, NGC Models Only):  
A. 2-Line LCD Display: Displays menus and information concerning the com-  
puter controller.  
Top line: Displays menu items.  
Bottom line: Displays menu options or information. For example,  
information about an astronomical object, such as a planet, or  
information about locating an object.  
B. Enter Button: Accesses, in order, the next menu or option. When a menu  
option you wish to choose displays, press ENTER to select it. This button is  
similar to a computer's RETURN key.  
C. Mode Button: Press this button when you wish to return to the previous  
menu. The MODE key is similar to a computer's ESCAPE key.  
If MODE is pressed and held for two seconds or more, the following informa-  
tion displays:  
• Astronomical coordinates of a selected object  
• Local Time and Local Sidereal Time (LST)  
• Timer and Alarm Status  
Press MODE again to return to the previous menu.  
D. Up/Down Button: Use UP/DOWN to scroll through the letters of the alpha-  
bet, numerical digits, menus, menu options and other information.

F. Vertical Slow Motion Control Knob: Use this control to make fine adjust-  
ments in the vertical movement of the telescope.  
G. Aux Port: Use this port, along with the optional #506 Astrofinder Software and  
Cable Connector Kit, to connect to your PC, or to update celestial objects for  
your control panel from the Meade website (www.meade.com). See  
OPTIONAL ACCESSORIES, page 19, for more information.  
F Optical Tube Attachment Knobs: Attach these knobs to the bolts on the optical  
tube when you attach the optical tube to the bracket. See HOW TO ASSEMBLE  
YOUR TELESCOPE, page 8, for more information.  
G Viewfinder: Before looking at an object in the eyepiece, locate the object in the  
viewfinder. The viewfinder provides a much easier way to locate celestial objects  
than a telescope eyepiece, because it has a much wider field of view.  
H Eyepiece: Place the eyepiece into the 90° diagonal mirror (8, Fig. 1 or 28, Fig. 4)  
and tighten the thumbscrew (25, Fig. 4) to a firm feel only. You may also place the  
eyepiece directly into the focuser drawtube (9, Fig. 1). Use the focus knobs (10,  
Fig. 1) to focus the eyepiece.  
I 90° Diagonal Mirror, Style 1: Holds the eyepiece at a convenient angle for easy  
viewing. Slide the diagonal mirror into the focuser drawtube (9, Fig. 1) and tighten  
the thumbscrew (26, Fig. 4) to a firm feel only.

1) Focus Knobs: Use to move the telescope’s focuser assembly to obtain precise  
image focus. Rotate the focus knobs clockwise to focus on distant objects, and  
counterclockwise to focus on nearby objects.  
1! Tripod Leg Nuts and Bolts (3): Attach the tripod legs (15, Fig. 1) to the tripod  
head (16, Fig. 1) using these three nuts and bolts. See HOW TO ASSEMBLEYOUR  
TELESCOPE, page 8, for more information.  
1@ Tripod Struts: Attach the struts to accessory tray. See HOW TO ASSEMBLEYOUR  
TELESCOPE, page 8, for more information.  
1# Tripod Leg Lock (3): Lift the lock to loosen the inner section of a tripod leg and  
extend the inner leg to the desired height. Press the lock down to lock the leg  
again.  
1$ Accessory Tray: Use the tray to hold extra eyepieces during your observing ses-  
sions.  
1% Tripod Legs: Attach the legs to the tripod head (16, Fig. 1). See HOW TO ASSEM-  
BLEYOURTELESCOPE, page 8, for more information. When observing, spread the  
legs out as far as they will open for a secure viewing platform.  
1^ Base/Tripod Head: Supports the telescope for placement on the tripod. See HOW  
TO ASSEMBLE YOUR TELESCOPE, page 8, for more information.  
1& Dew shield: Reduces the formation of dew on the telescope's primary lens and  
acts as a shade for daytime use.  
1* Battery Compartment Lid (NGC Models Only): Remove the lid to install one  
user-supplied 9v battery in this compartment. See HOW TO ASSEMBLE YOUR  
TELESCOPE, page 8, for more information.  
1( Compass/Bubble Level NGC Models Only): Use the compass to locate North  
while aligning the telescope. See EASY ALIGNMENT, page 12, for more informa-  
tion. Note that the compass is positioned next to an arrow etched onto the base.  
When the arrow of the compass and the etched arrow both point in the same  
direction, the telescope is then pointed North.  
NOTE: Sometimes air  
gets trapped below the  
compass dial causing  
the compass to not  
work properly.  
Use the bubble level to help level the base of your tripod. When the bubble is in  
the center of the compass, the base is level.  
Gently tap the battery  
cover to insure that no  
air is trapped below the  
compass dial.  
2) Horizontal Slow Motion Control Knob (NGC Models Only): Use this control to  
make fine adjustments in the horizontal movement of the telescope.  
2! Viewfinder Lens: Gathers light for the viewfinder.  
2@ Viewfinder Alignment Screws: Adjust these screws to align the viewfinder. See  
ALIGNING THE VIEWFINDER, page 9, for more information.  
2# Viewfinder Eyepiece and Rubber Cup: Turn the viewfinder eyepiece, if neces-  
sary, to focus the viewfinder. The rubber cup may be removed, if so desired.  
2$ Viewfinder Bracket: Holds the viewfinder in place. Attach to the optical tube. See  
HOW TO ASSEMBLE YOUR TELESCOPE, page 8, for more information.

How to Assemble Your Telescope  
Fig. 5: Attach tripod legs to the tripod  
Note that although the telescope is unassembled, all of the more difficult or compli-  
cated sections of the instrument are already factory pre-assembled. To set up the tel-  
escope, follow this procedure:  
head.  
1. Identify: Remove from the gift box and identify the telescope’s components,  
using the listing above.  
2. Tripod setup: The tripod is shipped with the tripod head and the tripod legs unat-  
tached. Attach the 3 aluminum tripod legs (15, Fig. 1) to the tripod head (16, Fig.  
1) with the 3 leg locks facing inward. Three 1 9/16" long bolts and hex nuts are  
provided for this purpose. See Fig. 5. Spread the tripod legs evenly apart.  
3. Attach the accessory tray: Your telescope comes supplied with one of two dif-  
ferent tray styles.  
Style 1: Attach the accessory tray (14, Fig. 1) to the leg brace supports (12, Fig.  
1) using the three provided 3/8" long screws and the wing nuts. Place the acces-  
sory tray on top of one of the leg brace supports of the tripod so that the mount-  
ing screw passes through the hole at one of the corners of the accessory tray,  
and through the slot in the leg brace support. Then thread-on the wing nut and  
tighten the screw using the provided screwdriver tool. See Fig. 6. Repeat this  
procedure until all 3 corners are mounted to the 3 leg braces.  
Fig. 6: Tighten screws with screwdriver  
tool to attach tray to the struts (Style 1).  
Style 2: Attach the inner support struts to the tripod legs using the provided pins.  
Line up the cylinder on the end of each strut between the holes on the bracket  
on each tripod leg. Use a large pliers to squeeze the pins into the bracket assem-  
bly. See Fig. 7. Place the tray (14, Fig. 1) over any one of the inner support struts.  
Line up the bolts on the tray with the bolt holes on the strut. Slide the two pro-  
vided bolts through the top of the bolt holes and tighten with the included wing  
nuts on the bottom side of the tray (Fig. 8). Tighten to a firm feel only.  
Note: This style tray does not have to be removed when you collapse the tripod  
at the end of a viewing session.  
Style 3 (Round Tray): See APPENDIX B, page 24.  
4. Set tripod leg height: Lift the tripod leg lock (13, Fig. 1) and extend the sliding  
center portion of the adjustable height tripod leg (15, Fig. 1) to the desired length.  
Press the leg lock down to lock.  
Fig. 7: Attach pin to tripod leg bracket  
with a large pliers (Style 2).  
5. Attach the optical tube to bracket: Your telescope comes supplied with one of  
two styles of optical tube attachment.  
Style 1: Two bolts extend from the center portion of the optical tube (2, Fig. 1).  
Slide the bolts through the holes in the bracket (3, Fig. 1). Thread the provided  
attachment nuts over the bolts and tighten to a firm feel. See Fig. 9a.  
Style 2: Unthread the cradle lock knob to open the cradle ring. Place the optical  
tube into the cradle ring. Tighten the lock knob so that it holds the tube loosely.  
Balance the tube: Slide the tube back and forth until you find a position where the  
tube remains horizontal (i.e., without tipping up or down). Now tighten the cradle  
ring lock knob to a firm feel. See Fig. 9b.  
Note: If the horizontal and/or vertical movement of the optical tube seems to  
be too loose or too tight, you can adjust the amount of tension in the move-  
ment of the tube to suit your own preference. See ADJUSTING THE  
HORIZONTAL AND VERTICAL TENSION OF THE OPTICAL TUBE, page 20.

6. Insert the diagonal mirror and eyepiece: Insert the diagonal mirror (8, Fig. 1)  
into the focuser drawtube (9, Fig. 1) and a low-power eyepiece (e.g., 25mm or  
26mm eyepiece) into the diagonal mirror. Tighten the eyepiece and diagonal mir-  
ror thumbscrews (25 and 26, Fig. 4) to a firm feel.

Attachment  
Nuts  
Note: Some models are supplied with one of two styles of the 90° diagonal  
mirror. Quantities of eyepieces and eyepiece size varies with each model.  
7. Install battery (NGC Models Only): Lift the lid of the battery compartment (18,  
Fig. 2) and attach a 9v battery (user-supplied) to the connector provided in the  
compartment.  
8. Remove dust cap: Pull to remove the dust cap from the end of the telescope.  
Replace it on the telescope at the end of the observing session. The cap keeps  
the telescope lens free from dust and foreign particles when it is not in use.  
Aligning the Viewfinder  
Because the main telescope has a fairly narrow field of view, locating objects directly  
in the main telescope can sometimes be difficult. The viewfinder (6, Fig. 1) is a small,  
wide-field telescope with crosshairs that permits you to more easily locate objects.  
When the 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 also positioned  
within the field of the main telescope.  
Fig. 9a: Attach optical tube to the  
mount (Style 1).  
Lock  
Knob  
Cradle  
1. Attach viewfinder bracket (Style 1): Remove the two attachment thumbscrews  
from the optical tube. These screws are pre-threaded at the factory into the opti-  
cal telescope tube at the viewfinder location. Line up the holes in the viewfinder  
bracket with the holes on the tube and thread the thumbscrews back onto the  
main tube. See Fig. 10a.  
Attach viewfinder bracket (Style 2): Using a Phillips head screwdriver, thread  
the two attachment screws in the bracket (these screws are placed inside the  
bracket at the factory) into the mating threads on the optical tube. See Fig. 10b.  
2. Attach viewfinder: Remove the rubber cup from the viewfinder tube and slide  
the tube into the viewfinder bracket. Orient the viewfinder as depicted in Fig. 4.  
Loosely tighten the collimation screws. You will use these screws to align the  
viewfinder; see TO ALIGNTHE VIEWFINDER, below. Re-attach the rubber cup onto  
the viewfinder.  
Fig. 9b: Attach optical tube to cradle  
ring (Style 2).  
3. Focusing the Viewfinder: Turn the viewfinder eyepiece on its internal thread.  
Generally a few turns are sufficient to achieve proper focus.  
To Align the Viewfinder:  
It is recommended that you perform steps 1 and 2 of this procedure during the day-  
time and step 3 at night.  
1. If you have not already done so, place a low-power (e.g., 25mm or 26mm) eye-  
piece in the diagonal mirror of the main telescope (8, Fig. 1) and point the tele-  
scope at an easy-to-find land object (e.g., the top of a telephone pole). Turn the  
focuser knob (10, Fig. 1) so that the image is sharply focused. Center the object  
precisely in the main telescope’s field of view.  
2. Then, looking through the viewfinder, turn some or all of the viewfinder’s align-  
ment screws (22, Fig. 4) until the viewfinder’s crosshairs point precisely at the  
same object as centered in the main telescope. The viewfinder is now aligned to  
the main telescope. Now tighten the screws to hold the tube securely; be careful  
not shift the tube's alignment.  
Fig. 10a: Attach viewfinder to the opti-  
cal tube (Style 1).  
3. Check this alignment on a celestial object, such as the Moon or a bright star, and  
make any necessary refinements.  
Choosing an Eyepiece  
A telescope’s eyepiece magnifies the image formed by the telescope’s main optics.  
Each eyepiece has a focal length, expressed in millimeters, or "mm." The smaller the  
focal length, the higher the magnification. For example, an eyepiece with a focal length  
of 12.5mm has a higher magnification than an eyepiece with a focal length of 25mm.  
Fig. 10b: Attach viewfinder to the opti-  
Low-power eyepieces (e.g., a 25mm or 26mm eyepiece) give a wide, comfortable field  
of view with high image resolution. High-power eyepieces (e.g., a 12.5mm or 4mm eye-  
piece) provide a smaller field of view but higher magnification when seeing conditions  
permit.  
cal tube (Style 2).

Low power eyepieces offer a wide field of view, bright, high-contrast images, and eye  
relief during long observing sessions. To find an object with a telescope, always start  
with a low power eyepiece (e.g., 25mm or 26mm eyepiece). When the object is locat-  
ed and centered in the eyepiece, you may wish to switch to a higher power eyepiece  
to enlarge the image as much as practical for prevailing seeing conditions.  
NOTE: Seeing conditions vary widely from night-to-night and site-to-site.  
Turbulence in the air, even on an apparently clear night, can distort  
images. If an image appears fuzzy and ill-defined, back off to a lower  
power eyepiece for a more well-resolved image (Figs. 11a and 11b).  
The power, or magnification of a telescope is determined by the focal length of the tel-  
escope 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. E.g., a 25mm eye-  
piece is used with a NGC60 telescope. The focal length of the NGC60 is 700mm (see  
SPECIFICATIONS, page 21).  
Focal length ÷ Eyepiece focal length = Power  
700mm ÷ 25mm = 28  
The eyepiece power, or magnification is therefore 28x.  
Simple Observations  
If you wish to observe a distant land object, such as a mountain top, you can observe  
by merely pointing the telescope and looking through the eyepiece.  
Move your telescope to observe distant street signs, mountains, trees and other  
structures. Use your viewfinder to help site-in on an object.  
Practice focusing objects with the focus knob (10, Fig. 1).  
Once you get a feel for how your telescope moves and focuses, try to view some-  
thing 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. You'll find that you will need to reposition your telescope from  
time to time to keep an object in the eyepiece field of view. This is especially true when  
using high-power eyepieces.  
Viewing terrestrial objects requires looking along the Earth's surface through heat  
waves. These heat waves often cause loss of image quality. Lower power eyepieces,  
such as 25mm or 26mm eyepieces, 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.  
If you have an NGC model telescope, you can locate stars and other celestial objects  
(over 1400 objects in all) using the control panel. In order to do so, you must initialize  
the control panel, set the telescope in the home position, and align the telescope. The  
control panel uses this information to determine the location of celestial objects.  
TIPS for Beginners  
Too Much Power?  
Can you ever have too much power? If the type of power you’re referring to is  
eyepiece magnification, yes, you can! The most common mistake of the begin-  
ning observer is to "overpower" a telescope by using high magnifications 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 Figs. 11a and 11b). Powers  
above 200X should be employed only under the steadiest atmospheric condi-  
tions.  
Fig. 11a & 11b: Jupiter; examples of  
the right amount of magnification  
and too much magnification.  
Most observers should have three or four additional eyepieces to achieve the full  
range of reasonable magnifications. See OPTIONAL ACCESSORIES, page 19.

11. The time display now reads "11:30:00PM."  
Easy Alignment (NGC Models Only)  
1. Easy Align: Once the control panel is initialized, the control panel automatically  
begins the Easy Alignment procedure.  
2. Set Home Position: The control panel prompts you to set the telescope in the  
home position. To set your telescope in the home position:  
Adjust the length of the legs of the tripod until the bubble in the bubble level  
is in the center of the compass.  
Rotate the base of the telescope until the arrow in the compass points in  
the same direction as the arrow etched into the base. The telescope is now  
pointing North.  
NOTE: Sometimes air  
gets trapped below the  
compass dial causing  
the compass to not  
work properly.  
Push down the front end of the optical tube (the end with the dew shield)  
until it stops.  
Gently tap the battery  
cover to insure that no  
air is trapped below the  
compass dial.  
When you have finished setting the telescope in the home position, press  
ENTER.  
3. Star Alignment: After the home position is entered, the control panel searches  
its database for two alignment stars, and displays "Searching" while it does so.  
The control panel uses these stars to orient itself to the sky. Once it is oriented,  
it knows the location of any celestial object in its database.  
For example, the control panel may search its database and choose Alkaid, the  
tail star of the Big Dipper, as the first alignment star. It displays "Ctr. Alkaid" on  
the top line and "Then Press Enter" flashes three times on the second line. This  
is a reminder that after you center a star in the eyepiece (see step 5 below), you  
need to press ENTER. But do not press ENTER yet.  
After displaying "Then Press Enter," the control panel displays two numbers on  
the second line. For example: "Ctr. Alkaid: +35 -115." These two numbers are  
called "displacement numbers" and will assist you in locating a celestial object.  
Note: If the horizontal  
and/or vertical move-  
ment of the optical  
tube seems to be too  
loose or too tight, you  
can adjust the amount  
of tension in the move-  
ment of the optical  
tube to suit your own  
preference. See  
4. Move the telescope: Move the telescope tube to the right or left and you will  
notice the first displacement number getting larger or smaller. Move the tube in  
the direction that makes the number smaller. Keep moving the tube until the num-  
ber nears zero. As you near zero, bars appear on the display to make it easier to  
precisely reach zero. Use the horizontal slow motion control (20, Fig. 2) to move  
the tube in small increments.  
After the first displacement number displays zero, move the tube upwards until  
the second displacement number also nears zero. As you near zero, bars appear  
on the display to make it easier to precisely reach zero. As you near zero, use  
the vertical slow motion control (F, Fig. 3) to move the tube. You probably will  
need to make fine adjustments with both displacement numbers as moving the  
optical tube may slightly shift one or the other displacement numbers.  
ADJUSTING THE  
HORIZONTAL AND  
VERTICAL TENSION OF  
THE OPTICAL TUBE,  
page 20.  
After both number have reached zero, the first alignment star may not appear in  
the field of view of the eyepiece. However, the alignment star should be easily  
recognized and be the brightest star in the area of the sky where the telescope  
is pointing. Look for the star in the viewfinder to see if you can locate it. The  
viewfinder has a wider field of view than the eyepiece. See WHICH ONE'S THE  
ALIGNMENT STAR, page 13, for more information.  
NOTE: The control  
panel locates alignment  
stars based on the  
date, time, and location  
entered. The alignment  
stars may change from  
night to night.  
5. Center the Star: Once you locate the star, adjust the optical tube using the hor-  
izontal and vertical slow motion controls until the star is visible and centered in  
the eyepiece. When the star is centered, press ENTER.  
6. Repeat the procedure for the second alignment star. If you have have followed  
the procedure correctly, "Align Successful" displays and the telescope is aligned.  
You may now use the control panel to locate other stars and objects in the sky. If  
your alignment was unsuccessful, "Align Unsuccessful" and then "Setup: Easy  
Align" displays. Press ENTER and repeat the procedure.

Go To Saturn (NGC Models Only)  
After performing the Easy Alignment procedure, the telescope is aligned for a night of  
viewing.  
IMPORTANT NOTE:  
As you observe  
IMPORTANT NOTE: Once aligned, do not move the telescope's tripod  
and base from the level position or alignment will be lost.  
Saturn, you will notice  
that the image moves  
in the eyepiece. This is  
because the Earth is  
rotating. You can use  
the horizontal and ver-  
tical slow motion con-  
trols (20, Fig. 2 and F,  
Fig. 3) to re-center the  
image in the eyepiece.  
The image will move  
much faster if you are  
using a higher-pow-  
ered eyepiece such as  
a 4 mm or the 12mm  
eyepiece.  
This exercise demonstrates how to select an object for viewing from the control  
panel's Object menu. The control panel provides an Object menu which displays a list  
(sometimes called a database) of over 1400 objects you can view with your telescope.  
This example demonstrates how to select Saturn from the list.  
NOTE: Saturn is not visible the entire year and you may need to choose  
another object from the Object menu list; however, the procedure, as  
described below, remains the same.  
1
After the telescope is aligned, "Select Item: Object" displays. Press ENTER.  
2. "Object: Solar System" displays. Press ENTER.  
3. "Solar System: Mercury" displays. Keep pressing UP/DOWN until "Solar System:  
Saturn" displays.  
4. Press ENTER. "Calculating" displays. "Saturn" and its R.A. and Dec. coordinates  
display. See APPENDIX A: ADVANCED FEATURES, for information about celestial  
coordinates.  
5. Press ENTER. Next, Saturn's displacement numbers display: "Saturn: +14 -135."  
NOTE: Your displacement numbers will be different than the ones in this  
example. Displacement numbers are determined by location, time, and  
date.  
6. Move the telescope tube to the right or left until you notice the first displacement  
number getting smaller. Keep moving the tube until the number reaches zero. As  
you near zero, use the horizontal slow motion control (20, Fig. 2) to move the opti-  
cal tube.  
Next, move the tube upward or downward until the second displacement number  
also reaches zero. As you near zero, use the vertical slow motion control (F, Fig.  
3) to move the optical tube. If you performed the alignment procedure correctly,  
Saturn will appear in your eyepiece. You may need to center the image.  
7. If you wish to display information about Saturn, press MODE and then keep  
pressing UP/DOWN to scroll through various lines of information. The last line of  
information displays as a scrolling message. As the message scrolls, you can  
press UP or DOWN to increase or decrease the scrolling speed.  
Using the Guided Tour (NGC Models Only)  
The control panel provides a Guided Tour menu that displays the best objects (and  
their displacement numbers) to view on any given night of the year. This example  
demonstrates how to use the "Tonight’s Best" Guided Tour. Other Guided Tours are  
also provided.  
TIPS for Beginners  
Which One’s the Alignment Star?  
If the control panel 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?  
The rule of thumb is that an alignment star is usually the brightest star in that  
area of the sky. If you're not sure if you have located the alignment star or it isn't  
in the eyepiece, look through your viewfinder. When you view an alignment star  
in the viewfinder, it stands out dramatically from the rest of the stars in that por-  
tion of the sky. The viewfinder will help you locate a star more quickly than the  
eyepiece, because it has a much wider field of view than the eyepiece.  
If you have an obstruction, such as a tree or a building blocking your view of the  
alignment star, or if you have any doubts at all about the star that has been cho-  
sen, no problem. Just press UP/DOWN and the control panel will find another  
star to align upon.

TIPS for Beginners  
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.  
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.  
Try not to use a standard flashlight. Experienced observers use red LED flashlights  
or tape red cellophane over their flashlights to use 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. Do not shine a flashlight  
into the telescope while someone is observing!  
Dress warmly. It gets chilly when you’re sitting for prolonged periods, even on  
warm 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.  
Use a 25mm or 26mm eyepiece to view terrestrial objects and wider areas of  
space, such as open star clusters. Use optional higher power eyepieces, such as  
a 12.5mm eyepiece (see OPTIONAL ACCESSORIES, page 19, for more details),  
when you wish to view something up close, such as craters on the Moon or the  
rings of Saturn.

MENUS  
How to move through menu options (NGC Models Only):  
IMPORTANT  
It is helpful to understand that menu selections are set in a loop  
.
This means that press-  
NOTE: No matter  
how many levels of  
menus are traveled,  
each press of the  
MODE key moves  
up a level, until the  
top level, "Select  
Item," is reached.  
Once in the Select  
Item level, press  
MODE to return to  
the topmost level,  
"Select Item:  
ing the DOWN button scrolls down through all the available options within a given cat-  
egory, then returns to the first option. Pressing the UP key scroll up through the options  
in the opposite order. Note that this capability is a quick way to get to an option that is  
near the bottom of the list. The following example demonstrates this capability.  
To navigate to the "Select Item: Setup" menu option when the "Select Item: Object"

Object Menu  
Almost all observing is performed using the Object menu category. (NOTE: Exceptions  
include Guided Tour and Landmark Survey. See GO TO SATURN, page 13, for an  
)
example of observing using the Object menu. Also see USINGTHE GUIDEDTOUR, page  
13.  
The Object Menu includes:  
Solar System is a list of the eight planets (Earth is not included) in order out from the  
Sun, followed by the Moon, asteroids, and comets.  
Constellation is a list of all 88 Northern and Southern Hemisphere constellations.  
When this option is chosen and a constellation name displays (e.g., "Constellations:  
Aquarius"), press ENTER to select the constellation. You can use UP/DOWN to dis-  
play lines of information about that constellation on the second line of the display.  
Press ENTER when the name of a constellation is displayed to display the name of  
the brightest star in the constellation. Use UP/DOWN to cycle through the list of  
important stars in the constellation (these are generally the stars that make up the

Min. (Minimum) of Algol is the minimum brightness of the dramatic eclipsing binary  
star system, Algol. It is relatively close at a distance of 100 light years. Every 2.8 days  
during a 10-hour period, Algol undergoes a major change in apparent magnitude as  
one of the two stars passes behind the other. The combined magnitude of the two stars  
thus dips from +2.1 to a minimum of +3.4 halfway through the eclipse as the second  
star is hidden. The computer control panel calculates minimum magnitude time at mid-  
eclipse.  
NOTE: The equi-  
nox and the sol-  
stice are the days

OPTIONAL ACCESSORIES  
A wide assortment of professional Meade accessories is available for the NG-Series  
and NGC-series telescopes. Consult the Meade General Catalog for complete  
details of these and other accessories.  
Eyepieces (1.25" barrel diameter): For higher or lower magnifications with the tele-  
scopes that accommodate 1.25" eyepieces, Meade 3-element Modified Achromatic  
eyepieces, available in focal lengths of 9, 12, 25, and 40mm, provide a high level of  
image resolution and color correction at an economical price. Alternately, at slightly  
higher prices, Meade 4-element Series 3000 Plössl eyepieces yield wider fields of  
view with excellent edge-of-field corrections and are available in a range of focal  
lengths including 5, 6.7, 9.5, 16, 25, and 40mm.  
#126 2x Barlow Lens (1.25"): For telescopes that accommodate 1.25" eyepieces, the  
Barlow lens doubles each eyepiece power while maintaining excellent image correc-  
tions. For example, a 25mm eyepiece used with an NGC60 telescope yields a power  
of 56X.  
#928 45° Erecting Prism: The 90° diagonal provided with some telescope models  
results in upright-but-reversed viewing of land subjects. The #928 45° Erecting Prism  
(1.25") orients the image correctly in terrestrial applications and provides a comfort-  
able 45° viewing angle.  
Camera Adapter: NG-series and NGC-series telescopes may be used for through-  
the-telescope photography of the Moon and planets or for terrestrial objects. For eye-

MAINTENANCE AND SERVICING  
General Maintenance  
Your telescope is a precision optical instrument designed to yield a lifetime of reward-  
ing applications. Given the care and respect due any precision instrument, your tele-  
scope will rarely require factory servicing or maintenance. Maintenance guidelines  
include:  
1. Avoid cleaning the telescope’s optics. A little dust on the front surface of the tele-  
scope’s lens causes virtually no degradation of image quality and should not be  
considered reason to clean the lens.  
2. When absolutely necessary, dust on the front lens should be removed with gen-  
tle 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.  
3. 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. A single drop of  
biodegradable dishwashing soap may be added per pint of solution. Use soft,  
white facial tissues and make short, gentle strokes. Change tissues often.  
CAUTION: Do not use scented, colored or lotioned tissues as damage  
could result to the optics.  
4. If your telescope is used outdoors on a humid night, telescope surfaces may  
accumulate water condensation. 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 being packed away. Do not, however, wipe  
any of the optical surfaces. Rather, simply allow the telescope to sit for some time  
in warm indoor air, so that the wet optical surfaces can dry unattended. In addi-  
tion, the dust cap should not be placed back on to the optical tube until the tele-  
scope is thoroughly dry.  
5
If your telescope is not to be used for an extended period, perhaps for one month  
or more, it is advisable to remove the 9v battery from inside the base. Batteries  
left installed for prolonged periods may leak, causing damage to the telescope’s  
electronic circuitry.  
Horizontal  
adjustment  
nut  
6. Do not leave your telescope outdoors on a warm day or inside a sealed car for  
an extended period of time. Excessive ambient temperatures can damage the  
telescope’s internal lubrication and electronic circuitry.  
Adjusting the Horizontal and Vertical Tension of the Optical  
Tube  
If the horizontal and/or vertical movement of the optical tube seems to be too loose or  
too tight, you can adjust the amount of tension in the movement of the optical tube to  
suit your own preference. To adjust the horizontal tension of the optical tube, use an  
adjustable wrench or nut driver to tighten or loosen the horizontal adjustment nut  
located under the base of the telescope. See Fig. 13.  
To adjust the vertical tension of the optical tube, first loosen the attachment knobs (5,  
Fig. 1) and remove the optical tube from the bracket (3, Fig. 1). Use an adjustable  
wrench or nut driver to tighten or loosen the vertical adjustment nut located on the  
inner side of the bracket. See Fig. 14. Check the amount of tension by moving the  
bracket up and down before reattaching the optical tube.  
Fig. 13: Horizontal adjustment nut.  
(View of the underside of the base.)  
Storage and Transport  
When not in use, store the telescope in a cool, dry place. Do not expose the instru-  
ment to excessive heat or moisture. It is best to store the telescope in its original box.  
If shipping the telescope, use the original box and packing material to protect the tel-  
escope during shipment.  
When transporting the telescope, take care not to bump or drop the instrument; this  
type of abuse can damage the optical tube and/or the objective lens.

Troubleshooting  
Unable to see an image through the eyepiece:  
Confirm that the dust cap has been removed from the telescope.

(Bracket shown with optical tube  
removed.)  
Images through the eyepiece appear unfocused or distorted:  
The magnification used may be too high for the seeing conditions. Back off to a  
lower power eyepiece. See TOO MUCH POWER? page 10.

If inside a warm house or building, move outside. Interior air conditions may distort  
terrestrial or celestial images, making it difficult, if not impossible, to obtain a sharp  
focus. For optimal viewing, use the telescope outside in the open air instead of  
observing through an open or closed window or screen.  
If viewing a land object on a warm day, heat waves distort the image. See SIMPLE  
OBSERVATIONS, page 10.  
For clear viewing of objects, turn the focus knob (10, Fig. 4) slowly since the "in-  
focus" point of a telescope is precise. Turning the focus knob too quickly may cause  
the focus point to pass without notice.  
The optics within the telescope need time to adjust to the outside ambient temper-  
ature to provide the sharpest image. To "cool down" the optics, set the telescope  
outside for 10 to 15 minutes before observing begins.  
A terrestrial object appears reversed left-for-right:  
The 90° diagonal mirror yields this image orientation. To view a correctly oriented  
image, the optional #928 45° Erecting Prism is required. See OPTIONAL ACCES-  
SORIES, page 19.

TIPS for Beginners  
Star Charts  
Star charts and planisphere are very useful tools. In particular, they are a  
great aid in planning a night of celestial viewing, as well as assisting in locat-  
ing celestial objects.  
A wide variety of star charts are available in books, in magazines, on the inter-  
net and on CD Roms. Meade offers AstroFinderand other star locator soft-  
ware. Contact your Meade dealer or Meade's Customer Service department  
for more information.  
Astronomy and Sky and Telescope magazines print star charts each month  
for up-to-the-minute maps of the heavens.  
The Norton Star Atlas and Reference Handbook by A. Norton and Sky Atlas  
2000 by W. Tirion and R. Sinnot are two of the most popular star charts on the  
market.

APPENDIX A: ADVANCED FEATURES  
Celestial Coordinates  
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 sys-  
tem of latitude and longitude on Earth surface maps.  
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  
for the celestial sphere. These lines are known as Declination and Right Ascension.  
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. 15) is that point in the sky where an exten-  
sion of the North Pole intersects the celestial sphere. The North Star, Polaris, is located  
very near the North Celestial Pole (1, Fig. 15). The celestial equator (2, Fig. 15) is a pro-  
jection 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 lon-  
gitude, 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 Ring Nebula (M57) by its Right Ascension (18hr) and  
its Declination (+33°).  
I
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 merid-  
ian. 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 (Dec.): This celestial version of latitude is measured in degrees, arc-min-  
utes, and arc-seconds (e.g., 15° 27' 33"). Dec. locations North of the celestial equa-  
tor 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."

Entering Coordinates for Objects not in the Database  
Although your computer control panel contains a database of more than 1400 celestial  
objects (stars, nebulae, planets, etc.) that you can observe, you may eventually want to  
view objects that are not part of the database. The computer control panel provides a fea-  
ture that allows you to enter an object's R.A and Dec. coordinates in the "User: Objects"  
option of the Object menu.  
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 your local library, computer store, book-  
store, 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:  
1. Make sure the computer control panel has been initialized and the telescope has been  
aligned.  
2. After the telescope is aligned, "Select Item: Object" displays. (If necessary, use  
UP/DOWN to scroll through the menus, as previously described, to find this option.)  
Press ENTER.  
3. "Object: Solar System" displays. Keep pressing UP/DOWN until "Object: User Object"  
displays and press ENTER.  
4. "User Object: Select" displays. Press UP/DOWN until "User Object: Add" displays.  
Press ENTER.  
5. "Name" displays on the top line and a blinking cursor on the second line. Use  
UP/DOWN and ENTER, as previously described, to enter the name of the object you  
wish to add to the database.

6. "Right Asc.: 00.00.0" displays. Use UP/DOWN and ENTER to enter the digits for the  
Right Ascension coordinate of your object.  
7. "Declination: +00°.00'" displays. Use UP/DOWN and ENTER to enter the digits for the  
Declination coordinate of your object. If necessary, use UP/DOWN to change "+" to "-  
."  
8. The computer control panel then prompts you to enter the size of the object. This step  
is optional. Use UP/DOWN and ENTER to enter the size (in arc-minutes), if so  
desired, and press ENTER to go to the next display. If you do not wish to enter this  
information, simply press ENTER.  
9. The computer control panel then prompts you to enter the magnitude of the object. This  
step is also optional. Use UP/DOWN and ENTER to enter this information, if so desired,  
and press ENTER to go to the next display. "User Object: Add" displays again.  
To Go To a user-entered object:  
In this procedure, you will choose an object from the User Object list and locate the object.  
1. With "User Object: Add" displayed, press UP/DOWN until "User Object: Select" dis-  
plays. Press ENTER.  
2. Use UP/DOWN (if necessary) to scroll to the desired object. Press ENTER.  
3. The name of the object and the Right Ascension and Declination coordinates display.  
Press ENTER. The displacement numbers for the object display.  
4. Use the displacement numbers as previously described (see page 12) to locate the  
object.  
Landmarks  
This menu option allows you to define and store terrestrial objects in the Landmark data-  
base. First, a landmark needs to be stored in memory using the "Landmark: Add" option.  
To view a landmark, use the "Landmark: Select" option. Landmarks may also be viewed  
using the "Landmark Survey" option in the Utilities menu.  
To Add a landmark to the database:  
In this procedure, you will store the location of terrestrial landmarks in memory.  
1. Set the telescope in the home position, if necessary. Note for future reference where the  
telescope is located.  
2. Select the "Select Item: Setup" menu.  
3. Press UP/DOWN until "Select Item: Object" displays. Press ENTER. "Object: Solar  
System" displays.  
4. Press UP/DOWN until "Object: Landmarks" displays. Press ENTER. "Landmark:  
Select" displays.  
5. Press UP/DOWN until "Landmark: Add" displays. Press ENTER.  
6. "Landmark Name" displays. Using UP/DOWN and ENTER, enter a name for the land-  
mark you wish to add to the database.  
7. "Center Landmark. Press Enter" displays. Move the optical tube to the desired land-  
mark and center the object in the eyepiece. Press ENTER. The object is now stored  
in memory.  
8. "Landmark: Add" displays. If you wish to add more landmarks, repeat steps 5 through

APPENDIX B: ALTERNATE TRAY ASSEMBLY  
Introduction  
Leg brace  
Some NGC/NG models are now shipped with a third style tray. The third style assem-  
bles with a round accessory tray.  
Assembly  
Use the provided 3 short screws, 3 washers and 3 bolts to attach the round  
accessory tray to the tripod. You will need a Phillips-head screwdriver to perform  
this assembly.  
Line up one of the leg braces (see Fig. 16) between the opening of one of the tri-  
pod leg brace supports on the tripod so that a screw will be able to pass through  
both the holes of the leg brace support and holes of the leg brace.  
Leg brace support  
Using a Phillips-head screwdriver, thread one of the short screws through the  
holes. Place a washer on the other end, followed by the matching nut. Tighten to  
a firm feel. Repeat this procedure until all 3 leg braces are mounted on the 3 leg  
brace supports. See Fig. 16.  
Fig. 16: Attach the leg  
braces to the leg brace  
supports.  
To attach the accessory tray to the leg braces, place the round accessory tray  
over the mounting bolt hole (Fig. 17). Thread the attachment knob into the the  
mounting hole on top of the tray (Fig. 17) and turn the knob clockwise (Fig. 18).  
Tighten to a firm feel, but do not overtighten—you will need to remove the tray if  
you wish to collapse the tripod. To remove the tray, just rotate the knob counter-  
clockwise and remove the knob. You can then lift and remove the tray.

BASIC ASTRONOMY  
In the early 17th century, Italian scientist Galileo, using a crude telescope smaller than  
your NG or NGC, turned it to look towards the sky instead of distant trees and moun-  
tains. What he saw, and what he realized about what he saw, forever changed the  
way mankind thought of 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 realized Earth's  
movement and position around the Sun, and in doing so, gave birth to modern astron-  
omy. 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 deter-  
mined how to measure the distance to stars; Edwin Hubble proposed a glimpse into  
the origin of the universe; Albert Einstein unraveled the relationship of time and light.  
Almost daily, using sophisticated successors to Galileo's crude telescope, such as the  
Hubble Space Telescope and the Chandra X-Ray telescope, more and more myster-  
ies of the universe are being solved 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 telescope, keep in mind Galileo. To him, a telescope was  
not a mere machine of glass and metal, but something far more—a window of incred-  
ible discovery.  
The Glossary  
Be sure to make use of the Glossary feature in your NGC computer control panel. The  
Glossary menu provides an alphabetical listing of definitions and descriptions of com-  
mon astronomical terms. Access directly through the Glossary menu or through  
hypertext words. See GLOSSARY MENU, page 17, for more information.  
Objects in Space  
Listed below are some of the many astronomical objects that can be seen with your  
telescope:  
The Moon  
The Moon is, on average, a distance of 239,000 miles (380,000km) from Earth and is  
best observed during its crescent or half phase when Sunlight strikes the Moon’s sur-  
face at an angle. It casts shadows and adds a sense of depth to the view (Fig. 19).  
No shadows are seen during a full Moon, causing the overly bright Moon to appear  
flat and rather uninteresting through the telescope. Try using 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.  
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.  
Fig. 19: The Moon. Note the deep  
shadows in the craters.  
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 due to the depth and force of a meteor or comet impact.  
Twelve Apollo astronauts left their bootprints on the Moon in the late 1960's and early  
1970's. 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 tele-  
scope on Earth are about one-half mile across.  
Planets  
Planets change positions in the sky as they orbit around the Sun. To locate the plan-  
ets on a given day or month, consult a monthly astronomy magazine, such as Sky  
25

and Telescope or Astronomy. Listed below are the best planets for viewing through  
your telescope.  
Venus is about nine-tenths the diameter 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.  
Mars is about half the diameter 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 coloring 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 39 moons (Io, Europa,  
Ganymede, and Callisto) can be seen as "star-like" points of light when using even  
the lowest magnification (Fig. 20). These moons orbit Jupiter so that the number of  
moons visible on any given night changes as they circle around the giant planet.  
Fig. 20: Jupiter and its four largest  
moons. The moons can be observed in  
a different position every night.  
Saturn is nine times the diameter of Earth and appears as a small, round disk with  
rings extending out from either side (Fig. 21). 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.  
Titan, the largest of Saturn’s 30 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:  
Fig. 21: Saturn has the most extensive  
ring structure in our Solar System.  
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 pin-  
points of light, irrespective of the size of the telescope used.  
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. 22).  
Numerous stars are visible.  
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.  
Fig. 22: The Pleiades is one of the  
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.
