    I cannot get ASTAP, which always worked perfectly for me, to resolve the images with the new 11" telescope with more than 2800 mm focal length (2989 due to the added accessories) and with the ASI 1600 MM Pro camera with 3.8 micron pixels.
    With PixInsight, Platesolve3 and others like Astrometry I have no problems and they resolve them well.
    Any idea of how the system should be configured, please?

    Thanks
    Leo Peiro

    Hi Leo,

    For such a long focal length, you will need the D80 database and expose maybe 20 seconds exposure or longer.

    Can you share one of the images which failed, so I can have a look. You find it in this path:

    Nina:

    The latest Beta (2.0 H1 BETA0008) will move failed solves to a sub folder in %localappdata%\NINA\Failed.
    To prevent unnecessary cluttering it will only create one file per appstart, target name and solver type (blind or not blind) and auto clean the folder for everything older than 7 days

    You can copy this path %localappdata%\NINA\Failed into Windows file explorer. Also share the small .ini file in the same directory

    Han
