I'm located on the southern side of Sydney... light pollution is moderate to the south and tragic to the north.
LP filters are not useful with CCD's. I use a standard Baader RGB set.
CCD's behave quite differently to DSLR's as you have quite a bit more dynamic range, with significantly less noise. Hence it's not difficult to pluck usable signal from a good deal of light pollution.
