11.. IINNTTRROODDUUCCTTIIOON

Thank you for purchasing this Celestron Newtonian Telescope. This telescope is a precision scientific
instrument. With it you will enjoy numerous objects in the sky—planets, nebulae, star clusters, galaxies and
other astronomical objects.

This manual covers both the 76mm equatorial mount model and the 114mm models. The equatorial mount
contains setting circles and slow motion cables to make it easier to locate and track astronomical objects.

But, before your journey begins take time to read this manual to familiarize yourself with the operation and
parts of your telescope.

WARNING—NEVER LOOK AT THE SUN WITH YOUR TELESCOPE OR ITS FINDERSCOPE.
PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT AS WELL AS DAMAGE
TO YOUR TELESCOPE. HOWEVER, YOU MAY ENJOY LOOKING AT THE SUN IF YOU
HAVE A SAFE METHOD OF DOING SO, SUCH AS A CELESTRON SOLAR FILTER.

Please refer to Figure 1 (and the identifying parts list) as you assemble the telescope.

A. The telescope and all items are packed in one box. Included with all models are:

• Telescope Optical Tube

• German Equatorial Mount

• Adjustable Tripod

• Star Pointer Finderscope and Bracket

• Counterweight Shaft and Counterweight

• Tripod Accessory Tray

• Declination Cable

• Right Ascension Cable

• 20mm Eyepiece - 1¼"

• 10mm Eyepiece - 1¼"

• The Sky® CD-ROM

To set up the tripod, locate the German equatorial mount, the tripod legs, the tripod mounting hardware and
the tripod accessory tray.

1. Extend the center portion (#35) of each of the three tripod legs down 6-8".

2. Use the three tightening screws (#34) to secure each of the extended legs by threading these screws
through the holes in the brackets at the bottom of each leg. It is important that you extend the legs
before the equatorial mount is attached, otherwise the inner legs may become difficult to slide down.
Fine tuning of the tripod height can be done later, and the tightening screws can be adjusted to secure
the telescope at the desired height

3. Slide the two top portions of each tripod leg around the sides of each flange on the tripod head

(#38) of the equatorial mount, so the flange is secured between them.

4. Slide the screw through the tripod leg and flange, until the screw extends out the other side.

5. Slide the washer and the nut over the screw and tighten. This can be left slightly loose, to allow

for positioning the legs later, when attaching the accessory tray.

6. Repeat this process for the remaining two legs. Now the tripod will stand by itself.

You are now ready to attach the tripod accessory tray.

7. The tripod tray fits over the holes in the tripod leg brace. Insert the winged bolts through the holes

in the bottom of the tripod leg brace and thread them into the holes in the accessory tray. Tighten
all bolts to ensure proper stability to the mount.

B. Before proceeding further, locate Right Ascension (#24) and Declination knobs (#22) and tighten them
finger tight.

1. Locate the declination cable holder (#13). Locate the declination cable (the shorter of the two

cables) and attach the cable (#18) to the cable holder by tightening the thumb screw on the cable
end. The thumb screw should be tightened down hard on the flat surface of the cable holder after
backing off the cable about 1/4" from being fully engaged. This method helps ensure there is no
slippage when using the cable.

2. You may reverse the position orientation of the Declination

cable to suit your preference if desired.

3. Locate the right ascension cable holder (#27). Locate the right

ascension cable (#31) and attach it the same way as the
declination cable was attached in the last section.

Before mounting the optical tube, the counterweight must be

attached to the mount:

1. Slide the counterweight shaft (#29) through the counterweight

(#30). Use the counterweight lock to lock the counterweight in
place. By holding the counterweight in one hand, thread the
counterweight shaft clockwise into the equatorial mount as
shown in figure 1.

C. Now you are going to put the telescope optical tube (#11) onto the equatorial mount.
For models #31041 and #31044:

1. Slightly loosen the screws that hold the mounting rings on the telescope in place.

2. Slide the rings apart so that each is at the same distance as the holes in the mounting platform.

3. Place the telescope tube on the mount so that the flat portion of the tube rings rest on the mounting

platform.

4. Align the holes on the square extrusions with the holes at the ends of the mounting platform.

5. Starting with the ring closest to the focuser end of the tube, insert the bolt through the hole in the

mounting platform and thread it into the mounting ring. Repeat this process for the remaining
mounting ring.
