How To Set Up
Assembly:
Note: We recommend assembling your telescope for the first time in the daylight or in a lit room so that you can familiarize
yourself with assembly steps and all components.
1. General Information regarding Assembly, Positioning
Before beginning with the assembly, choose a suitable position for your telescope.
It will help if you assemble this apparatus at a spot from where you have a clear view of the sky, a sturdy
surface beneath you, and enough space.
Important: Tighten screws only as much as you can by hand - do not “over-tighten“ the screws.
2. Tripod
Take the three-legged tripod and set it vertically on the floor with the feet pointing downwards. Now take
two of the tripod legs and pull these legs carefully out away from each other, until they have reached
their fully opened position. During this time, the entire weight of the tripod rests on one leg. Finally, set
the tripod down on all legs, so that it stands straight.
Loosen the three locking clips on the tripod legs, pull each individual tripod leg out until it has reached
the desired length close up the locking clips and set the tripod down on a sturdy, even surface.
NOTE: A small water level on the accessory tray can help you position your tripod horizontally.
3. Mounting The Tray
The accessory tray must be positioned with its flat side down in the middle of the tripod leg brace, and
then must be mounted by turning it 60° in a clockwise direction.
The three projections on the tray plate must match up to the mounting brackets on the division bars
(and must snap into place. If necessary, you may push the tripod leg brace down-wards a little.
Now set the tube (and holder) onto the mount with the objective opening in the direction marked
(N-marking on the tripod head, north point and telescope figure on the mount). Then fasten the tube
holder with the clamping screw of the dovetail adapter on the mount head.
4. Inserting the Eyepiece
Two Plossl eyepieces 26 mm and 9.7 mm come with your telescope. With the eyepieces, you can control
the magnification of your telescope.
Before installing the eyepieces and the focuser, take the lens cap out of the eyepiece holder.
NOTE: Make sure the focuser is closest to the object which you are trying to view. If the focuser is not
closest to the object the telescope is facing backwards and the view will not of the ground and dark or
black.
5. Flexible shafts
In order to facilitate the exact fine adjustment of the declination- and right ascension shafts, the flexible
shafts have been placed on the holders of both these shafts, in the places designed for that purpose.
The long flexible shaft is mounted parallel to the telescope tube. It is secured with a clamp screw on the
designated indentation on the shaft.
The short flexible shaft is mounted sideways. It is secured with a clamp screw on the designated
indentation on the shaft. Your telescope is now ready for use.

Telescope Terms To Know:
Diagonal: A mirror that deflects the ray of light 90 degrees.
With a horizontal telescope tube, this device deflects the light upwards so
that you can comfortably observe by looking downwards into the eyepiece.
The image in a diagonal mirror appears upright, but rotated around its
vertical axis (mirror image).
Focal length: Everything that magnifies an object via an optic lens has a certain focal length. The focal
length is the length of the path the light travels from the surface of the lens to its focal point. The focal
point is also referred to as the focus. In focus, the image is clear. In the case of a telescope, the focal
length of the telescope tube and the eyepieces are used to determine magnification.
Lens: The lens turns the light that falls on it around in such a way so that the light gives a clear image in
the focal point after it has traveled a certain distance (focal length).
Eyepiece: An eyepiece is a system made for your eye and comprised of one or more lenses. In an
eyepiece, the clear image that is generated in the focal point of a lens is captured and magnified still
more.
Magnification: The magnification corresponds to the difference between observation with the naked
eye and observation through a magnifying device like a telescope. If a telescope configuration has a
magnification of 30x, then an object viewed through the telescope will appear 30 times larger than it
would with the naked eye. To calculate the magnification of your telescope setup, divide the focal length
of the telescope tube by the focal length of the eyepiece.
Using/Aligning the Red Dot Viewfinder:
The viewfinder is powered by a CR-2032
battery that is included. Before using the
viewfinder for the first time, remember to
remove the plastic insulator that is blocking
the battery from connecting.
When it is time to replace the battery,
remove the battery cap by loosening the set
screw. Take out the old battery and slide a
new battery in place with the positive side
showing. Replace the cap, and tighten the
set screw.
For The Viewfinder To Be
Effective, It Must Be Aligned. To
do this:
• Insert the 26 mm eyepiece into the
diagonal and power on the viewfinder by
sliding the switch on its right side to an
“On” position.
The Red Dot Viewfinder is
powered by a battery type
CR-2032 (3V); if a replacement is
necessary, remove cap (Fig. 1) by
unscrewing set screw (Fig. 2) and
sliding battery towards the front.
Slide new battery in place with the
positive (+) side showing. Replace
cap and tighten with
set screw (Fig. 2).

• Point the eyepiece at an easy to identify target like a telephone pole that is approximately 200 yards
away. Center the object in the eyepiece. Lock the telescope into place by tightening the panhandle.
• Without moving the telescope, position the red dot using the two adjustment screws so that it shares
the same view as the one in your eyepiece. The front screw will move the viewfinder up and down, and
the other will move it side to side. Your viewfinder is now aligned.
Note: To preserve battery life, don’t forget to turn off the viewfinder after use.
Using Your Telescope:
After you have assembled your telescope, you are ready to start observing. Put the 26 mm eyepiece
into the diagonal to get the widest field of view. This wider field of view will make it easier to locate
and track objects.
To move the scope up, down and side to side, loosen the locking screws slightly and grip the telescope
near where the tube meets the focuser and steadily move the tube until your target comes into view
in the eyepiece. Once you have found and focused on your desired target, you can lock the telescope
into position by tightening the two locating screws. It is important to remember that the rotation of the
Earth means objects will move out of your eyepiece fairly quickly.
For a closer look at an object, you can insert the 9.7 mm eyepiece. The magnification will increase
from 20x to 52x.
Cleaning:
Your telescope is a precision optical device and keeping the optics free of dust and dirt is crucial for
optimal performance. To clean the lenses (objective and eyepiece) use only a photo-grade soft brush
or a lint-free cloth, like a microfiber cloth. Do not press down too hard while cleaning, as this might
scratch the lens. Ask your parents to help if your telescope is really dirty. If necessary, the cleaning
cloth can be moistened with an optical glass cleaning fluid and the lens wiped clean using very little
pressure. Do not use harsh detergents!
Make sure your telescope is always protected against dust and dirt.
After use, leave it in a warm room to dry off before storing.
Possible Objects For Observation:
Terrestrial Objects
Take note of the examples below, including Mount Rushmore and the
golf course. Start with the 26 mm eyepiece and focus until the image
is clear. After mastering the 26 mm eyepiece, switch to the 9.7 mm
eyepiece and practice scanning and focusing until the image is clear.
Choose several terrestrial objects to practice focusing on, but never
point your telescope at or near the sun, or you risk blindness.

The Moon
Diameter: 3,476 km
Distance: Approximately 384,401 km
The Moon is the Earth’s only natural satellite, and it is the second brightest object
in the sky (after the Sun). Although it is our closest neighbor, a lot of people
have never really taken a good long like at the Moon. With your telescope, you
should be able to see several interesting lunar features. These include lunar
maria, which appear as vast plains, and some of the larger craters. The best views will be found
along the terminator, which is the edge where the visible and cloaked portions of the Moon meet.
Orion Nebula (M 42)
M 42 in the Orion constellation
Right ascension: 05:35 (Hours: Minutes)
Declination: -5:22 (Degrees: Minutes)
Distance from Earth: 1,500 light years
Located about 1,500 light years from Earth, the Orion Nebula (Messier 42, abbreviation: M 42) is the
brightest diffuse nebula in the sky – visible with the naked eye, and a worthwhile object for telescopes of
all types and sizes, from the smallest field glass to the largest earthbound observatories and the Hubble
Space Telescope.
When talking about Orion, we‘re actually referring to the main part of a much larger cloud of hydrogen
gas and dust, which spreads out over half of the Orion constellation. The expanse of this enormous
cloud stretches several hundred light years.
Ring Nebula (M 57)
M 57 in the Lyra constellation
Right ascension: 18:53 (Hours: Minutes)
Declination: -33:02 (Degrees: Minutes)
Distance from Earth: 2,400 light years
The famous Ring Nebula M 57 in the constellation of Lyra is often viewed as the prototype of a planetary
nebula; it is one of the magnificent features of the Northern Hemisphere’s summer sky. Recent studies
have shown that it is probably comprised of a ring (torus) of brightly shining material that surrounds the
central star (only visible with larger telescopes), and not of a gas structure in the form of a sphere or
an ellipsis. If you were to look at the Ring Nebula from the side, it would look like the Dumbbell Nebula
(M27). When viewed from Earth, we are looking directly at the pole of the nebula.
Dumbbell Nebula (M 27)
M 27 in the Fox constellation
Right ascension: 19:59.6 (Hours: Minutes)
Declination: -+22:43 (Degrees: Minutes)
Distance from Earth: 1,360 light years
The Dumbbell Nebula (M 27) in Fox was the first planetary nebula ever discovered. On July 12, 1764,
Charles Messier discovered this new and fascinating class of objects. We see this nebula almost directly
from its equatorial plane. If we could see the Dumbbell Nebula from one of its poles, we would see the
shape of a ring, and we would see something very similar to what we know as the Ring Nebula (M 57). In
reasonably good weather, we can see this object well even with low magnifications.
