Ok, so I ran these myself and they solved in 0.2 and 0.3 seconds with the G18 database. It seems that however
these images were generated, they were generated with a small enough FoV that they didn't include enough stars
that were in the G17 database.
Okay I'll try that. Thanks.

Does G17 mean the stars have a 17th magnitude limit? (PinPoint solved it with a mag 15 limit.)

Right, but ASTAP is under active development. As was pointed out earlier in this thread, there have
been fixes
even since I used it last. It's possible that if the problem is there (and we still don't know that, it could
be SGP), that
it's already been fixed.



Is it correct that the latest version is a *beta* version? (v0.9.421) It is free now, but will it be free when it is
released as v1.0?

I just downloaded it, installed it and the G17 database. I then used APPM's NASA SkyView camera type to
get an emulated image, which solved in PinPoint in a few seconds. Trying to solve the same image in ASTAP fails
despite that it seemed to extra the correct RA/Dec and image scale from the FITS header.

Any idea of what I should check? Or is this a possible bug in the application?
