When importing RAWs from my Olympus E-PL6, the imported FITS also have only 12 bit resolution. Well, yes, my Olympus has a 12 bit sensor. But when processing a sequence of pictures the resulting stacked picture also has roughly 12 bit resolution. OK, I could have used "Sum stacking", but I really wanted to use "Average stacking with rejection".
Would it be possible to scale the pictures at import? E.g. FITS created by Kstars/Ekos from a 12 bit camera are also scaled to 16 bit.
Kind Regards and Clear Skies
