Description

I have always wanted to go after this nebula and was finally up in Michigan which is much darker than my home site (20.8 compared to 18.0) but only got 4 hours on it. Three hours of HA and one hour of OIII to make an HAOIII image. Combined 30% HA with OIII for the Blue Channel and used the straight OIII for green so star colors are not accurate but at least fairly pleasing.
