A few first impression comments about the suggestions. Working my way through them.
ASTAP intiates a Windows Defender warning.
Calibration Intro Tutorial for Tycho Tracker seems to suggest it’s for moving targets.
I have installed AstroImageJ, found the DP button but there is no option to process flat darks.
So I have found various tutorials but I’m getting the impression they are for CCDs which do use bias frames I believe.
Trying not to be too negative but I think I need something with very basic tutorials that walks you through it.
