NGC 6914 - HaRGB

NGC 6914 is a reflection nebula with a bluish cast located approximately 6,000 light-years away in the constellation of Cygnus. It can be separated into three main regions: 1) NGC 6914 in the center a.k.a. vdB 132, 2) NGC 6914a (to the left) a.k.a. vdB 131, and 3) NGC 6914b (to the right). Each bright nebula is being illuminated by one or more massive, young, hot star(s). This reflection nebula lies within a much larger hydrogen gas cloud which is being ionized by the ultraviolet light from the stars in the region. Several dark nebulae composed of gas and dust are also found within the region.

I had intended for this image to be an HOO (w/ RGB stars), however, the stacked oxygen data was out whack. The orientation was a bit off since I removed the camera during one of the sessions and there were terrible gradients that the flats did not remove.  I was imaging the OIII when the moon was out and when it was 'fake clear' nights so I was not surprised by results.  The Ha and RGB data came out really well so I just went with it.  The reflection nebula came out surprisingly well in RGB even without any luminosity. 

If you have been following me you know I have been busy with the Hyperstar lately and have two images posted so far, The Cave Nebula and The Crescent Nebula, however, I have not forgotten this setup.  I was done with this three weeks ago but have been very busy, in fact I have more unprocessed images as well.
