Question for the group. I have the ASI174 - love the camera, FYI. When I try to take darks regardless of software,(tried with Firecapture, Genika, and Nebulosity) I get a repetitive pattens across the whole screen. When I introduce a small amount of light, the pattern goes away. If you look at the attached images, you can see what I am talking about. The camera works great for solar so I'm not sure what I'm seeing. Any ideas?
