elevator clamp screw back on.
Loosen the vertical clamp (31) and set the
tube in a horizontal position. Screw the clamp

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.
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 obser-
vation; this will ensure that the temperatures
inside the tube have adjusted.
In addition, you should be careful to set your
telescope on a level, stable surface.

3. First time Set-up
Loosen the pole elevator clamp screw (28)
3@
and set the tilt plate (32) roughly to the latitu-
de of your location, according to the scale of
the latitude 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. Ger-
many lies between 54° (Flensburg) and 48°
(Munich) 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 latitude (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 informati-
on 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
telescope holder upwards 90° (white arrow
markings at the front of the mount will be
across from each other). Set the tube the
right way around (see telescope illustration
and north arrow) 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.
