I've messed about a bit using ASTAP on a laptop to live-stack images accumulating in a folder on my Pi 4 4GB running StellarMate 1.7.6.

Can something similar be done all on the Pi? I seem to recall running the ASTAP UI back when I was running a 32-bit SM OS, but never really had a need for it. I don't know if the GUI works reasonably well on the Pi 4 and if the stacking is performant enough to bother with. I also don't know if ASTAP shows the updated image in real time, or if I'd have to refresh a FITS or JPEG viewer periodically.

TIA,
