Introduction
Thank you for purchasing your 76mm Reflector Telescope. Your telescope is a precision
optical instrument which you can use to learn more about space, the study of astronomy,
and the world around you. Please read this manual before using your flash in order to get
the best results possible.
Introduction

Assembling Your Telescope
1.Remove the tripod legs from the box and
extend each of them to a suitable length from
top to bottom, and then tighten the locking
knob (see fig. 1).

-6-
Assembling Your Telescope (continued)
2. Connect each leg and the mount base using long
screws and wing nuts (see fig. 2a), but not tighten.
3. Stretch out the tripod legs so that you can put the
accessory dish on it, connecting them with short screws
and wing nuts (see fig. 3) . Tighten the wing nuts of the
tripod legs.
4. Connect the pitching shaft to the main tube using the
pitching shaft screw (see fig. 2b) .
5. Loosen the left and right blocks on the main tube, and
then connect the main tube to the main mount. Tighten
the right and left blocks (see fig. 2c) and tighten the
pitching clamp handle screw (see fig. 2d ).

-7-
Assembling Your Telescope (continued)
6. Take off the thumb nuts for the sighting scope , and
loosely insert the two bolts on the sighting scope
bracket so they are aiming the main tube into them.
Whirl the thumb nuts back and tighten them (see fig.
4a).
7. Install the eyepiece (or erecting eyepiece ) in the
eyepiece joint tube, tighten the locking screws (see fig.
4b ).

-8-
1. Eyepieces : Insert any of the eyepieces into the eyepiece joint tube and tighten the
locking screws. This will provide you with the optical power that you need.
2.The Sighting Scope : The sighting scope has a low magnification and wide visual field,
which can help you find far away objects quickly.
3. Erecting Eyepiece: Put the erecting eyepiece in the eyepiece joint tube, and tighten the
locking screw. The image you are viewing will be straighten out , but the image can be a bit
dim.
4. Moon Filter : Because there is a great deal of reflected glare when the full moon is
observed , the addition of the moon filter will remove this glare and make it possible to
sharpen surface details . At other times , this filter is unnecessary and a sharper image can
be obtained without it . The moon filter is screwed into the eyepiece in the same way that
the sun filter is added .
Using Your Telescope’s Accessories

-9-
The telescope is a precision optical instrument . The more you know about it, and the more
carefully you maintain it, the many service it will provide for you.
What you see through the telescope and whether you see clearly is dependant on three
factors: magnification , brightness and resolving power. There is a common misconception
that it would be better if the magnification is bigger at all times .While one of the most
important functions of the telescope is to magnify, you must keep in mind that the effective
magnification is after all limited . For example if the magnificafion gets too big it will make
the image dim and the field of view narrow . So it is necessary to consider about the three
factors altogether.
Tips on Using Your Telescope

-10-
1. Hot air is always moving through the atmosphere .This motion can cause bad images in
high power conditions, which is why it is often preferred to observe at several night .
2. Hot air on the surface of the earth will also cause waves of the air to make the image
twisted and crushed . This can make the observing conditions very bad.
3. Light pollution : try hard not to use your telescope around street lights , or under your
home’s lights.
4 .Moonlight is another factor that affects tone’s observation , as the full moon or the bright
moonlight will make the stars and the planets nearby dim .
5. Be careful not to observe from open windows (or even through closed windows)
especially during winter when the temperature outdoors varies greatly compared to the
temperature indoors.
6. Clouds in the sky can hinder your observations , but fortunately these clouds will move
often .
7. Heavy fog can make observation impossible.
Factors That Effect Observing Results

-11- -12-
Maintaining Your Telescope
The mirrors and lenses arethe most important and the most easily damaged parts of your telescope. To
avoid affecting the precision and the performance of your optics, the mirrors or lens can't be casually
taken out of their mount and the lens or mirrors must be cleaned as carefully as possible.
Cleaning : When it becomes necessary to clean the lens or mirrors , you should first clean off any dust
with a suitable brush, and then drop a few drops of non-harsh cleaning fluid on a clean soft
cloth, and brush any remaining prints or dust.
