1. INTRODUCTION
Thank you for purchasing this Celestron 76mm (3") Tabletop 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.
The altazimuth mount is the simplest and easiest type of mount to use with two motions altitude (up and
down) and azimuth (side-to-side).
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.
2. TELESCOPE ASSEMBLY
Please refer to Figure 1 (and the identifying parts list) as you assemble the telescope.
The telescope and all items are packed in one box. Included are:
Model # 31034
• Telescope Optical Tube
• Table Tripod Mount
• Tripod Legs (3)
• 5x24 Finderscope and Bracket
• 4mm Eyepiece - .96" (150x)
• 20mm Eyepiece - .96" (30x)
• Barlow Lens - 2x - .96"
A. Remove the telescope tube, table tripod arm and tripod head from the box. These parts are assembled at
the factory:
1. Take the tripod legs (Q) out of the box. Attach the three tripod legs by threading them clockwise
into the threaded holes in the tripod head (P).
2. Rubber feet (R) are already installed on the tripod legs to prevent any damage from the metal
tripod legs when set on a table or other flat surface.
B. Mounting the finderscope:
1. Remove the finderscope assembly (finderscope and bracket) from the box.
2. The finderscope with bracket (G) mounts in a socket on the telescope tube. Slide the finderscope
bracket into the groove of the socket on the telescope and hold it in place by tightening the
thumbscrew (J) firmly.

C. Mounting the eyepiece:
1. Take the low power (20mm) eyepiece (A) from the box and remove it from the plastic vial.
2. Remove the plug up cap from the eyepiece holder (B).
3. Insert the eyepiece into the eyepiece holder and hold in place with the thumbscrews (C).
3. TELESCOPE OPERATION GETTING SET UP
A. To move the telescope in azimuth (side-to-side):
1. Loosen the clamp lock (O).
2. Hold a tripod leg (Q) and slowly rotate the telescope by turning the table tripod telescope arm (N)
to the desired location.
3. Lock the clamp lock (O).
B. To move the telescope in altitude (up-down):
1. Loosen the clamp lock (S).
2. Hold the rear housing (M) and slowly rotate the telescope to the desired location.
3. Lock the clamp lock (S).
C. To rotate the telescope tube:
1. Loosen the tube ring adjustment knob (H).
2. Rotate the telescope tube slowly by turning the optical window cell (I) to the desired location.
3. Tighten the tube ring adjustment knob (H).
D. To focus the telescope and align the finderscope:
1. Remove the front lens cap (I).
2. With a low power eyepiece tight in the eyepiece adapter, position the telescope tube to look at any
object about one mile or further away during the day. Put the object in the center of the field. To
focus, turn the focusing knob (D) until your chosen object is in sharp focus. Remember to use
outdoors only as you should not look through windows which may distort the image.
3. Look through the finderscope. If the object being observed is not visible in the finderscope or is
not in the center of the finderscope crosshairs, then you need to align the finderscope. Use the
finderscope adjustment screws (F) to align the finderscope with the main telescope by tightening
and loosening these screws until the object is centered on the crosshairs. Once the finderscope is
aligned with the main telescope, it makes it easy to find celestial objects. You find the desired
object in the finderscope first (since it has a wide field) and then look at the narrow field but much
more powerful main telescope for detailed views.
4. If the image in the finderscope is not sharp, then turn the finderscope eyepiece (E) until the image
is sharp.
5. Do not be alarmed when you look through the telescope and the object is upside down and
reversed left to right (the finderscope will only be reversed left to right). This is normal with an
astronomical telescope.
