5. Inserting the Eyepiece
2 eyepieces: 26mm and 9.7mm come with your telescope. With the
eyepieces, you can control the magnifi cation 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.
6. Aligning the Red Dot Finder scope
Your telescope is designed for terrestrial and astronomical observations.
Please keep in mind that heat turbulences in the air are also magnifi ed.
In warm conditions, it can be useful to limit observations to medium
magnifi cations. First, remove the dust cover from the objective lens.
Please make sure to remove plastic insulator from battery (picture
below). Insert the 26mm Eyepiece into the diagonal; you may now
adjust the focus with the draw tube’s wheel. The Red Dot Finder scope is
activated by sliding the switch on its right side; there are two intensities
available. Before the fi rst observation, the Red Dot Finder scope has
to be aligned to the telescope. For this, point at a striking target (e.g.
telephone pole) with the telescope’s eyepiece. Now, without moving the
telescope, switch on the Red Dot Finder scope and adjust the red dot
with the 2 adjustment screws (left and right - up and down) until it fi ts to
the eyepiece’s view. Now the Red Dot Finder scope is aligned and ready
to point for the telescope.
Never use a telescope to look at the sun! Looking at or near the sun
will cause instant and irreversible 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 viewfi nder at
or near the sun. Do not look through the telescope or its viewfi nder as it is
moving. Children should always have adult supervision while observing.
7. Flexible shafts
In order to facilitate the exact fi ne adjustment of the declination and right
ascension shafts, the fl exible shafts have been placed on the holders
of both these shafts, in the places designed for that purpose. The long
fl exible shaft is mounted parallel to the telescope tube. It is secured with
a clamp screw on the designat-ed indentation on the shaft. The short
fl exible 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.

Set-up
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 fl oor 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 (11) on the tripod legs, pull each individual
tripod leg out until it has reached the desired length close up the locking
clips (11) and set the tripod down on a sturdy, even surface.
TIP:
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 fl at 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 downwards
a little.
4. Connecting the tube
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 fi gure on the mount). Then fasten the tube holder with the
clamping screw of the dovetail adapter on the mount head.

toward the star (with the help of the flexible shafts), or you can adjust
the focus with the focus knob. Additionally, you can now switch to a
higher magnification by changing the eyepiece (to a smaller focal length).
Please be aware that the magnification of the stars is barely perceptible.
TIP: Eyepieces are lens systems designed for your eye. In an eyepiece,
the clear image that is generated in the focal point of a lens is
captured (in other words, made visible) and magnified still more.
Eyepieces with various focal lengths are necessary in order to achieve
various degrees of magnification. Begin each observation with an
eyepiece with a low magnification (large focal length, e.g. 26mm).
Finding stars
In the beginning, you will certainly find it difficult to orient yourself in the
sky, since stars and constellations are always moving, and their position
in the sky varies according to the season, date, and time. The North Star
is an exception to this. If you were to imagine the polar axis of the Earth
extending out into space, it would approximately hit the North Star. The
so-called north ce-lestial pole is the starting point for all star charts. On
the drawing you see a number of the more familiar constellations and
star clusters, which are visible throughout the year. The position of the
stars is, of course, dependent on date and time. If you have fixed your
telescope on one of these stars, you will notice that within a short time it
disappears from the eyepiece field of vision. In order to compensate for
this effect, operate the flexible shaft of the counterweight axis, and your
telescope will follow the ap-parent path of this star.
Storing the Telescope Hopefully your observation session will have been
interesting and successful; afterwards, it is recommended to store the
telescope in a dry and well-ventilated room. Please do not forget to
place the lens caps back onto the front tube opening and the eyepiece
holder. All eyepieces and optical accessories should also be stored in
their respective containers.
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 be of the ground and dark
or black.
Your telescope also include a Wi-Fi eyepiece, once you have your object
in view, you may exchange the 26 eyepiece for the Wi-Fi eyepiece.
After exchanging the eyepiece, please follow the below instructions for
operation of the Wi-Fi eyepiece on applicable Wi-Fi devices.

Possible objects for observation:
We have compiled and explained a number of very interesting celestial
bodies and star clusters for you but we suggest that you start practicing
during the day focusing on terrestrial objects such as birds and or
trees at varying distances from you. On the accompanying images at
the end of the instruction manual, you can see how objects will appear
in good viewing conditions through your telescope at varying powers
(see pictoral examples below).
Terrestrial Views
Please note the example picture of Mount Rushmore. Start with the
26mm Plössl eyepiece and focus until clear. After mastering the focus
with the 26mm change the 9.7mm eyepiece and practice focusing and
scanning until images become clear in the eyepiece. We have included
some additional examples that are possible with your telescope such as
a bird and a green on a golf course. DO NOT POINT YOUR TELESCOPE
DIRECTLY AT THE SUN OR BLINDNESS IS POSSIBLE.
The Moon
The moon is the Earth’s only natural satellite.
Diameter: 3.476 km
Distance: approx. 384 401 km
The moon has been known to humans since prehistoric times. It is the
second brightest object in the sky (after the sun). Because the moon
circles the Earth once per month, the angle between the Earth, the moon
and the sun is constantly changing; one sees this change in the phases of
the moon. The time between two consecutive new moon phases is about
29.5 days (709 hours).
Orion Nebula (M 42)
M 42 in the Orion constellation
Right ascension: 05:32.9 (Hours: Minutes)
Declination: -05:25 (Degrees: Minutes)
Distance: 1.500 light years
With a distance of about 1500 light years, the Orion Nebula (Messier 42,
abbreviation: M 42) is the brightest diffuse nebula in the sky – visible with
the naked eye, and a rewarding object for telescopes in all sizes, from
the smallest fi eld 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 with
over 10 degrees over the half of the Orion constellation. The expanse of
this enormous cloud stretches several hundred light years.
Ring Nebula in Lyra constellation (M 57)
M 57 in the Lyra constellation
Right ascension: 18:51.7 (Hours: Minutes)
Declination: -+32:58 (Degrees: Minutes)
Distance: 2.000 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 magnifi cent
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). With this object, we’re looking
directly at the pole of the nebula.
Dumbbell Nebula in the Vulpecula (Fox) constellation (M 27)
M 27 in the Fox constellation
Right ascension: 19:59.6 (Hours: Minutes)
Declination: -+22:43 (Angle: Minutes)
Distance: 1.250 light years
The Dumbbell Nebula (M 27) in Fox was the fi rst planetary nebula ever
discovered. On July 12, 1764, Charles Messier discovered this new and
fascinating class of objects. We see this object almost directly from its
equatorial plane. If you could see the Dumbbell Nebula from one of the
poles, it would probably reveal the shape of a ring, and we would see
something very similar to what we know from the Ring Nebula (M 57).
In reasonably good weather, we can see this object well even with small
magnifi cations.

Telescope ABC’s
What do the following terms mean?
Diagonal:
A mirror that defl ects the ray of light 90 degress. With a horizontal telescope
tube, this device defl ects 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 magnifi es an object via an optic (lens) has a certain focal
length (FL). The FL 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 FL of the telescope
tube and the eyepieces are combined.
Lens:
The lens turns the light which 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 magnifi ed still more.
There is a simple formula for calculating the magnifi cation:
Focal length of the telescope tube / Focal length of the eyepiece = Magnifi cation.
You see: In a telescope, the magnifi cation depends on both the focal length
of the telescope tube and the focal length of the eyepiece.
Magnifi cation:
The magnifi cation corresponds to the difference between observation with
the naked eye and observation through a magnifi cation apparatus (e.g. a
telescope). In this scheme, observation with the eye is considered “single”,
or 1x magnifi cation. Accordingly, if a telescope has a magnifi cation of 30x,
then an object viewed through the telescope will appear 30 times larger than
it would with the naked eye. See also “Eyepiece”.
Troubleshooting
Mistakes:
No picture
Blurred picture
No focus possible
Bad picture
Viewing object visible
in the fi nder, but not
through the telescope
Despite using star
diagonal prism
the picture is “crooked”
Help:
Remove dust protection cap
and sun-shield from the
objective opening.
Adjust focus with focus wheel.
Wait for temperature to
balance out.
Never observe through a
glass surface.
Adjust fi nder.
The star diagonal prism
should be vertical in
the eyepiece connection.
