Cygnus Wall

The Cygnus Wall!!!! This is 6 hrs of HA data combined with 1 hr of RGB stars. It's what we call an HARGB image. I did this to show the details in the pillars of Hydrogen that compromise the Cygnus Wall. This DSO is the main attraction of the North American Nebula in my opinion. Many stars have seen a birthplace in this dense region of space. It lies within the Milky Way Galaxy in the constellation Cygnus. Rich in oxygen and sulfur, the hydrogen which gives birth to stars in rich abundance is often drowned out by the layer of oxygen that lies above. By using narrow band Hydrogen Alpha filters we are able to see through the dense gaseous regions to the dense composites of hydrogen that dwell beneath. Who knows how many species of life may survive in these areas of star formation. It's interesting to speculate. The Cygnus Wall is one of my favorite deep sky objects. Wu-Tang 4 eva!!!
