Axes

The mounting consists of 2 perpendicular axes:

  • right ascension (1)
  • declination (2).

The right ascension axis is parallel to the Earth axis, pointing towards the northern/southern celestial pole on the northern/southern hemisphere, respectively. The declination axis points towards the celestial equator. The setup is described in a dedicated article.

Introductions to the general handling of the technology and to the usage of Maxim DL are of course also available.

The dome is made out of fibre-reinforced plastic (FRP). It was built 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.
