C11 & CGE PRO
The C11 is our second largest Schmidt Cassegrain telescope and suitable for mobile use. Every time
one likes to use it, one has to put it up again from scratch. The purpose of this article is to describe
the details of this process.
Scattered pieces
To protect the sensitive electronics from humidity and other harsh weather conditions they are stored
in the lab course room. The remaining mechanical parts stay in the dome, so that one does not need
to carry them around.
Stored in the dome:
1. the tripod
2. the tube (C11)
3. counterweights + bar
Stored in lab course room:
1. the CGE PROs electronic box
2. the CGE PRO mount
3. a box containing all 1.4" eyepieces and the corresponding filters
4. sun filters
Setup
1. The CGE PRO is a parallactic mount, which has to be adjusted to point to the northern celestial
pole. Therefore, the tripod (see

2. Now put the electronic box on the tripod (see

4. Screw the counterweight bar into the mechanics and place the counterweights on it (see
figure 6). When you fasten the screws on them, they are hold in place.
5. Connect the electronic box to the engines of the mount. The cables (see
