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:
the tripod1.
the tube (C11)2.
counterweights + bar3.
Stored in lab course room:
the CGE PROs electronic box1.
the CGE PRO mount2.
a box containing all 1.4″ eyepieces and the corresponding filters3.
sun filters4.
Setup
The CGE PRO is a parallactic mount, which has to be adjusted to point to the northern celestial1.
pole. Therefore, the tripod (see figure 1) should be positioned accordingly. To do so, it is usually
sufficient to point the tripod leg with the carrier for the hand terminal to the south.
Now put the electronic box on the tripod (see figure 2) and fix it with three bolts (see figure 3).2.
Place the mechanics of the CGE PRO (see figure 4) on the electronic box and fix it again with3.
three bolts (see figure 5). Due to the heavy weight of the mechanics, this step should be
performed by two people.
Screw the counterweight bar into the mechanics and place the counterweights on it (see4.
figure 6). When you fasten the screws on them, they are hold in place.
Connect the electronic box to the engines of the mount. The cables (see figure 7) go in the5.
ports on the side of the electronic box (figure 8). The cables have different lengths. The short
one connects electronic box with the right-ascension axis, while the longer one is for the
declination axis (see figure 9). The cables only fit in one position.
Now plug the energy supply (see figure 10) and the hand terminal (see figure 11) into the6.
corresponding ports (see figure 12).
The attachment of the tube should also be performed by two people. One inserts the dovetail7.
into the clamp of the mount (see figure 13 and figure 14) and holds it in place. The other one
