Some scopes will do a better job than others of rejecting off axis light pollution. I agree that there's not much you can do about LP that's inherent in the FOV though a fast scope, like Greg's RH, will allow you to achieve a high SNR faster for both wanted (target) and unwanted (light pollution) signal. The LP can then be removed as a gradient.
