Title: Light Pollution Filters
Post by: Roy on Nov 17, 2011, 20:27:09
Any recommendations for a good quality light pollution filter? The street lamps in our part of Sevenoaks seem to be a mixture of low pressure sodium and probably mercury vapour.

Cheers

I assume your mean for your DSLR Roy. 

I use a clip in CLS filter.
