-The OMS is accessible by means of the Remote Desktop Protocol (RDP). However, the login is restricted to the local IP address space. Thus, one first has to login to one of the Linux machines from the astro physics department preferentially via ssh. For the lab course, one can use the laboratory computer a12. A [[:en:praktikum:zugang|how-to]] explaining the ssh login is available. +The OMS is accessed using the Remote Desktop Protocol (RDP). However, login is restricted to the local IP address space. Therefore, you must first log in to one of the Linux machines of the astrophysics groups or establish an SSH tunnel to these machines. The columba evaluation computer can be used for the lab course. A [[[:en:praktikum:zugang|how-to]] explaining the SSH login is available.

 There are two basic things to keep in mind when changing instruments: First, the focuser has a limited range of adjustment, which means that different adapters (M68 thread) are needed for different instruments. In the [[en:ost:fokus_new | focusing]] article, we explain in more detail how to calculate the ideal adapter length and list the adapter lengths normally used for the most common instruments.  There are two basic things to keep in mind when changing instruments: First, the focuser has a limited range of adjustment, which means that different adapters (M68 thread) are needed for different instruments.

-In addition, the interchangeable balancing counterweights on the tube should be matched to the instrument (see table below). Several small 230g counterweights and a large 1kg counterweight are available. The latter is mounted on a rod on which it can be moved as required.

The rod holder remains attached to the tube at all times.
  
 The counterweights are located in the large metal cabinet. The small counterweights are screwed onto a counterweight holder, which usually has to be mounted first. When handling the counterweights at the front of the tube, the telescope should be positioned as close to the ground as possible to prevent the counterweights from falling into the tube when they are screwed on or off.  The counterweights are located in the large metal cabinet.
