I've started processing this image a few days ago in APP. I have noticed a Halo around the galaxy that shouldnt be their. I'm trying to figure out what may have caused it. Wondering if it could be from my flats? or Taking flats with filter in place or even with my Flattener/reducer.
I do live in a brothel 8+ area, hens why I use an L-Pro filter.
Does anyone have any suggestions?
