When I transfer subs from my flash drive taken with 294 MC pro into GIMP from the flash drive, I get some of them as RGB and some are Grey. Deep Sky Stacker will not stack all of them as they do not match. I am new to Astro Photography, and sure that I am doing something wrong. But, taking 60 subs and only getting to use 25 of them is getting old after a week of this. Any help?
