This has been bothering me in the sense that without feedback I cannot tell whether or not my camera's sensor is noisier than usual or faulty.
With longer exposures I get considerable noise the image often looks washed out and nothing like what you see through the scope, naturally I'm aware of the problem of noise is CCD camera's etc but how noisy should the image appear.
Also I've noticed dark lines appearing at either the top, sides and or bottoms of the images the longer exposure you take, is this normal??
