 A working solution is to set up the object detection (with ''detect.advanced'' ) so that it tries to determine the optimum aperture and stores it in the fits image keyword ''DET_APE''. ''detect.advanced'' normally does this, so just make sure that it is used. If you use ''detect.sexonly'' to gain speed, you may restrict detect.advanced only to the focusing target. A working solution is to set up the object detection (with ''detect.advanced'' ) so that it tries to determine the optimum aperture and stores it in the fits image keyword ''DET_APE''.

-Automatic focusing in RTS2 is solved using a combination of a observation scripts and observation processing. In particular, there is a special target which needs to be executed in order to (re)focus the telescope. +Automatic focusing in RTS2 is solved using a combination of observation scripts and observation processing.

 The other imaginable ways like ''rts2-scriptexec -d <CAMERA> -s "FO.FOC_DEF=<position>"'' works as well, but XML-RPC interface is the prefered way how to solve the problem. The other imaginable ways like ''rts2-scriptexec -d <CAMERA> -s "FO.FOC_DEF=<position>"'' works as well, but XML-RPC interface is the prefered way how to solve the problem.

   * we do not care if the astrometry is successfull, but obsproc mechanism by default does and does not provide a way to give us all images without complications. Disabling the astrometry and performing only object detection would improve the speed and overall processing.  -> disable the astrometry in the processing script? -> How many things would this break?   * we do not care if the astrometry is successfull, but obsproc mechanism by default does and does not provide a way to give us all images without complications.
