Description

My first test with the ASI290MM on a galaxy. I did expect higher quality but, as so often, my lack of experience is likely the cause. Anyway, revision B is the noisy DSS stack with Level stretch applied. Wondering whether the amount of background noise in the revision B image is "normal". After all, the camera is not cooled and is basically specified a "planetary" camera. The image is 2x drizzled.
