I have just bought Affinity today for stacking astro photo. I try to stack 2 set of photo. It's almost work except over exposure. I have investigate each image and saw that every of them look like the are +EV. You can see in attach file compare between individual open and in stack. Is that about raw conversion ? I have try with Sony A6300 raw and Panasonic GX8 raw which show the same over exposure in stack. s.pdf
