Quote:Thanks Scott, David. That's what I figured.
David - I ran across the comparison report between the Deep Sky, UHC, OIII, and H-Beta that you did some time ago. I was surprised at the degree of contrast enhancement the OIII gave on non-planetary nebula. For some reason I had gotten it in m my head that the OIII was primarily a PN filter.
