So, if you give ASTAP an ephemeris created by (say) JPL Horizons it align multiple images to keep the comet images stacked? Sounds nice.
I see it runs under Windows and Linux – under Linux it could use Astrometry.net for platesolving. How is it doing it under Windows – using the comet’s predicted RA/Dec as the centre to search for star patterns? Plus possibly a hint at sensor pixels size and system focal length?
How do you find it to use?
