I think the UHC works better in light polluted skies.
I have two filters that, as far as I can tell, do the same thing. One
is an O-III filter, and the other is an UHC filter. Both of these seem like they do the same thing. Can some one help me out in understanding what these are good for, and if both do the same thing?
Thanks. ++++++++++++++++++ Troy Davidson, KF7MTE www.istroyworking.com
