I am curious, why would stacking images of such faint objects give you a better overall image? I can understand that noise from high ISO can be somewhat negated, but are there other advantages to stacking standard wide angle night shots? I have a camera that I have used for some night sky photography away from a scope and they come out fine, but the light pollution and short shutter time makes for underwhelming looking images. I never thought to stack them though. Intriguing idea.
*EDIT* Faint spelling error correction.
