Hi all,
I have a Canon 600D modified using this
http://www.astrodon.com/products/fil...n_inside_dslr/, and was wondering if it's worth getting a light pollution filter? In the classifieds there's a Astronomik Cls and a Lumicon deep sky filter, would either of these be of use to me? I live about 10k's away from Perth cbd, and I'm mostly interested in imaging star clusters and galaxies.
Cheers,
Chris
