Quick run down of Siril

Bias/offset#
inherent noise of sensor Can be taken once and used for months Temp doesn't matter very much for most cams Take 20-40 frames with lens cap on, shortest exposure available, same ISO
Open Siril, set work dir, add all raws, convert (no debayer /!, keep all channels) Then stacking > median stacking, no normalisation
Dark#
Thermal noise during or After shooting (temp important), same params but with lens cap on
Open Siril, set work dir by clicking on "house" icon"), select sequence name (for instance, "neowise_dark"), add all raws, convert (no debayer /!, keep all channels)
Then go to stacking
basic#
Then stacking > median stacking, no normalisation
most optimal#
average stacking with rejection, no normalisation, Winsorized sigma clipping (if rejection ends up > 0.5%, fall back to median stacking, no norm)
Lights#
Simple photos of the object
In siril, change dir, set seq name, convert WITH debayer
Registration: registration method "Global star", else don't change settings
Comets#
Register sequence using global sking sequence tab, display first image, select comet, then using sequence tab again select last image et pick object in #2
