Shot M81 the last couple nights with my ASI294MM, LRGBSHO filter wheel, and AT60.
I've noticed on my Lum, Green, and Red frames I have these weird image artifacts. Can anyone Identify these? I assume they must be dust but was surprised my flat frames didnt remove them. could it be that my flat light is too bright?
The stretched image is attached for your viewing pleasure
Also... Can anyone tell me how to edit them out?
