Amazing image Greg. It can be seen that a lot of signal can be obtained in a relatively short time at f/3.65.

Greg,

That is an awesome image. I am not sure it gets any better than that!

Really nice image. I am curious though - how exactly do you "blend" the H-alpha in for a five-color image? Do you have that process written up somewhere?

Charlie
