Hi Ken and Jared,
I was doing some testing with ASTAP and SGP. SGP does not handle bad solves well.
SGP shows the ASTAP window trying rotation angles and never times out.
I took a .FIT file and clone stamped the stars randomly for some testing.
When I run ASTAP standalone it times out after a few second, SGP just keeps saying “Solving…”
Hopefully this will help with some debugging to solve this,
