Whats a good light pollution filter for imaging?

I am interested to hear what the consensus is on the best light pollution filter for imaging?

Also do you think focal length or F ratio of scopes is relevant when imaging in light polluted areas?

Do you need to take shorter exposures with CCD cams? I know you need to limit exposures with DSLRs otherwise you get the sky glow easily.

Greg.
