After approx. 20 minutes, you can begin with the
astronomical observation.
Do not observe from closed spaces, and set up
your telescope with the accessories approx. 30
minutes before beginning observation; this will
ensure that the temperatures inside the tube
have adjusted.
In addition, you should be careful to set your te-
lescope on a level, stable surface.
3. First time Set-up
Loosen the pole elevator clamp screw (28) and
set the tilt plate (32) roughly to the latitude of
your location, according to the scale of the lati-
tude control rod (29) - in Germany, this is about
50°. Point the part of the tripod with the North-
marking (N) in a northerly direction. The upper
side of the tilt plate will also be pointing north.
The latitude control rod will be pointing south.
4. Positioning of Geographical Latitude
From a street map, an atlas, or the Internet, find
out your location’s angle of latitude. Germany
lies between 54° (Flensburg) and 48° (Mu-
nich) north geographical latitude. Now loosen
the pole elevator clamp screw (28) and tilt the
tilt plate (32) until the number on the latitude
control rod (29) that is next to the clamp is the
same number as your location‘s angle of latitu-
de (e.g. 51°).
TIP:
The angle of latitude can always be found
in an atlas on the right side, or on the left
side of a map. You can get more informa-
tion at your city hall, your land registry of-
fice, or on the Internet: for instance, at
www.heavens-above.com. There, under “An-
onymous user > Select,” you can choose your
country; the relevant information will then come
up.
5. Final orientation
Turn the declination shaft (8) as well as the te-
lescope holder upwards 90° (white arrow mar-
kings at the front of the mount will be across
from each other). Set the tube the right way
around (see telescope illustration and north ar-
row) in the holder and tighten the clamp screw.
The eyepiece of the telescope is now pointing
at the ground; the objective lens is pointing at
the North Star. Loosen first the clamp of the
latitude control rod and then the clamp of the
declination shaft, and bring the North Star into
the middle of the eyepiece field of vision.
Finally, retighten the clamp. From this point
onward, the tripod may not be moved or ad-
justed because the orientation will be lost.
Loosen the pole elevator clamp screw (28) and
lower the tilt plate (30) until it is horizontal (in
other words, until it stops). Screw the pole ele-
vator clamp screw back on.
Loosen the vertical clamp (31) and set the tube
in a horizontal position. Screw the clamp back
on.

By turning both flexible shafts (14, 15) (Figure
1), the telescope can be moved horizontally and
vertically.

2. Set-Up (at night)
A dark location is very important for many ob-
servations, as bothersome lights (lamps, lan-
terns) can have quite a negative effect on the
detail and clarity of the telescope image.
If you leave a bright room at night to go outside,
your eyes need time to adjust to the darkness.
