Hello to anyone who would have an opinion..|
I am wanting to buy an Astronomik light pollution filter for use with a CCD refractor and CCD SCT LRGB setup. Should I get one to replace my L filter when shooting or should I get one to go forward of the filter wheel somewhere? I am leaning toward getting one to go in front of the filter wheel in the optic train somewhere..

|i use a Lumicon UHc..its very good. with heavy polution..narrowband filters will work better|

|I use a Chroma LP filter as my luminance in one of the rigs and the other uses a HUTEC IDAS, again as the luminance filter only. I thought long and hard about this and if I'd put the LP filter in the front of the imaging train then it may have had an adverse effect on my Narrown band data collection. I'm happy how it works|

I see the difference in some of the same shots you have taken that I have taken. My pollution is not bad, but I think it is probably borderline. I guess I am probably considering getting a substitute for the Lum filter at this point unless anyone responds with convincing info to the alternative. Thanks for the advice.

unfortunately I think that you can't have definitive answer to your question. A lot of people use an LP filter between filterwheel and telescope, others use an LP filter just on filterwheel (in place of L filter), other people don't use LP filter.
I know just one thing: everyone has problems!
personally I use an Idas P2 in place of L filter. some friend use Idas between telescope and OAG (so they can have LP reduction on RGB filters) but a lot of thimes they have reflection problems.
Sorry for my english :-)
