O'Meara is one of the foremost visual observers of our time (or any time, for that matter), and he does NOT use any kind of UHC or other filters for observing nebula! (It helps to live in Hawaii, I suppose...) Kind of an "anti-matter" version of Brent, who likes interference filters, but not color!" __________________________________ Do you Yahoo!? The New Yahoo!
