+===== Handling =====
+Introductions to the general [[en:ost:telescope:handling_new| handling of the technology]] and to the [[en:ost:ccds:maximdl| usage of Maxim DL]] are of course also available.
 ===== Dome =====
-The dome is made out of fibre-reinforced plastic (FRP). It was build and set up by Baader-Planetarium. The dome automatically follows the movement of the telescope. However, the azimuth, the hatch, and the shutter can be manually controlled by an infrared remote control.
