I'm starting with astrophotography and my DSLR produces CR2 raw images. I use Linux and want to stack series of shots and do RAW processing (curves, RGB balance, etc.) I googled and found software Iris and DeepSkyStacker, but I can't run them under Linux (it doesn't work with Wine). Is there any native software for my purposes?
I also googled RawTherapee and Darktable, but its interfaces cause my brain to burn out.
