    Thank you, Peter, for your help.

    You might want to start with the list of detected sources---the standalone version of astrometry.net provides this as a file.  It's simply a list of (x,y) coordinates in pixel space of each star that exceeds the detection threshold.  These can then be mapped to global (ra,dec) coordinates using the WCS (world coordinate system) that astrometry.net discovers.

    The online version produces these x/y and wcs fits-files which I could not read. If I understand you now correct the standalone version of astrometry.net creates and reads the corresponding fits-files directly after the analysis of the photo and does not require an other program to read these fits-file?
     
      Once you have these, I imagine a catalog query can get you catalog names for these sources; try SIMBAD:

    Thank you also for this link. The site is not new but I have not kept the link because I thought I wuld not have a need for it. A "supplementary detour" makes it now however necessary to analyse a few photos. I will see whether it is really necessary to install Stellarium for this task or not.
