- | - 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.

- | 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.
