NGC 6914 and vdB 132

These nebulae form the northern part of the γ Cygni nebulae. NGC 6914 is the name of the blue combined emission/reflection nebula around three stars near the center of the image, van den Bergh 132 designates the central one. Most of the other large red emission nebula patches in this image seem to belong to a huge supernova shell located in the next inner spiral arm of our galaxy. They are extremly faint.
