Description

Commonly referred to as the Butterfly Nebula, this region around Gamma Cygni is breathtaking. This is a wider field of my recent Heart of Gamma Cygni image. While I have posted an even wider field of the entire region, I have never isolated the Butterfly. One reason was I never really understood where the Butterfly was, which is evident by the fact that I clipped the tip of its left wing. Poor framing. Guess I have to reshoot it!. Now I have the gamut of widefield, middle field (this image) and an assortment of close in crops of various features found in this and the widefield versions. What can I say, I love Cygnus. I even have an LRGB/HaLRGB version but I could not do it justice....maybe one day.
