This stunning combination of both blue and yellow reflection, and pink emission nebulosity has few rivals in the fall sky. This field was very carefully chosen to include the nebulous open cluster at the upper right Dolidze 8 which is surrounded by NGC6914a, and the two main blue nebulas below which are NGC6914b in the center, and NGC6914 to its left. The background field is awash with an enormous amount of unnamed hydrogen nebulosity which I was able to bring out with some additional Halpha exposures.

Notice that there are some yellow reflection nebulas in this image. That color for a reflection nebula is quite uncommon in the sky, and warrants special attention in this region. Also, few if any other bright reflection nebulosites are present in Cygnus, this being one of the best.
