-There is a built-in focus/temperature self-correction to prevent frequent focusing during the operation. The focal offsets of various filters are not known and it is known that they are not treated within the existing solution. They are very likely to be small for the existing filter set, but may be of a concern if a custom filter is inserted. +<del>There is a built-in focus/temperature self-correction to prevent frequent focusing during the operation.</del> The focal offsets of various filters are not known and it is known that they are not treated within the existing solution.

 There is a basic set of Bessel filters. Custom filters of 50x50mm may be inserted upon request. There is a basic set of Bessel filters. Custom filters of 50x50mm may be inserted upon request.

 +We tested the focusing procedure, it's on ultra2:~/jelinek/focscr123, it works, produces images with columns of stars with different focuses. We have been told that within CAHA there is a program to tell the best focus out of such an image.

 +When running this script we get a ''Warning: interrupt in select function'' at the graphical screen. Weird.

 +The following scripting commands are executed at ''ultra2''.

 +From what I have seen they are all scripts which can be studied (and not really used literally). The level of support of programs based on what has been found inside is, however, likely to be different than if we use them as they are. On the other hand, connecting rts2 to epics would bring a serious simplification.
  
-These are commands to the mount and focuser. They are generally blocking commands which end when the requested action is finished. They return a single numeric value on a line to determine the exit status. (//We are missing examples of the output of each command at this moment.// The dome is entirely integrated with the telescope, there is no need to take care of it.+They are generally blocking commands which end when the requested action is finished.

 As I (mates) understood, this set of commands, although old as the others, has been recently revisited by Ulli Thiele when the telescope has been repaired and could, theoretically, be retouched if there are some issues. But we should not expect Ulli or anybody else do much effort here.  As I (mates) understood, this set of commands, although old as the others, has been recently revisited by Ulli Thiele when the telescope has been repaired and could, theoretically, be retouched if there are some issues.
