My thinking is that the 12" would still pick things up easier, but the image would not be as bright/contrasty (if such a word?). On the other hand the 8" in dark skies would show things crisper/bright?
I'm not even sure if there is a point to my question, just something I'm curious about.

well the more light pollution will be suffered in the big scope, but you also get more light of the object your after, as for the 8 performing better in dark skies, well its not physics your trying to defy its common sense. the skies are darker so you will see better, however, the bigger scope will make it easier to identify the object in the city sometimes, Just my experience with the 12" meade and a c8 celestron
