-====== C11 & CGE PRO ======+<WRAP group> 
 +<WRAP half column> 
 +Celestron's CGE PRO is a rugged, computer-controlled German equatorial mount suitable for both astrophotography and visual observation. With a generous payload capacity of up to 41kg, it can effectively accommodate large telescopes and heavy imaging equipment. The precision gears and motors allow for accurate tracking and alignment, although our model is getting older and no longer achieves such high precision. With autoguiding support, however, this is not noticeable.  
 +In addition, features such as the All-Star Polar Alignment and accessories such as the NexStar+ hand control and StarSense AutoAlign module allow the mount to be set up and aligned efficiently. 
  
-The C11 is our second largest 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. +===== Individual parts =====

 ===== Setup ===== ===== Setup =====
  
-  - The CGE PRO uses a parallactic mount, which has to be adjusted to point to the northern celestial pole. Therefore, the tripod (see <imgref stativ>) 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.+  - The CGE PRO is a parallactic mount, which has to be adjusted to point to the northern celestial pole.

   - Screw the counterweight bar into the mechanics and place the counterweights on it (see <imgref counterweight>). When you fasten the screws on them, they are hold in place.    - Screw the counterweight bar into the mechanics and place the counterweights on it (see <imgref counterweight>).

   - Connect the electronic box to the engines of the mount. The cables (see <imgref cables>) go in the ports on the side of the electronic box (<imgref ebox+connections>). 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 <imgref connected>). The cables only fit in one position.   - Connect the electronic box to the engines of the mount.

-The CGE PRO can simply switched on and off via the ''On/Off'' switch at the electronic box. In contrast to the OST, the CGE PRO does not require any shutdown procedure.

 ===== Alignment ===== ===== Alignment =====
  
-Usually it is required to create a new alignment after each setup of the mount. If one wants to use more than one night in a row, there is the opportunity to put the mount into a hibernation mode (see below) that allow to disconnect the mount from the power supply and at the same time to conserve the alignment. If the mount is used at a fixed position, one also can make use of a saved alignment. +Usually it is required to create a new alignment after each start of the mount.
