NGC 6914, VDB 131, VDB 132 Nebula
This image contain many different bright and dark nebula, but usually, this area that is comprised of the three blue reflection nebula, recognized as NGC6914. NGC6914 is a vast, beautiful nebula complex located in the center of Cygnus constellation and lies about 6000 light years from us. Although all of the three blue reflection nebula going under the same name as NGC6914B, NGC6914A and NGC6914C (from left to right), the middle one and the left one have their own designated name of different catalog by Van Den Bergh. They are vdb132 in the middle and vdb131 to the left.
This nebula complex was discovered by Jean Marie Edouard in 1881 and in 1966 Van Den Bergh added two of the three reflection nebula to his own VDB catalog. This image also contain objects from two other catalogs, LBN and LDN, which are Lynd's Bright and Dark nebula catalogs. I have marked them in Annotated version of the image. Also, the annotated version will discover the location of two peculiar objects , Parsamian 22 – small bipolar nebula and V1515 Cygni FU Orionis variable star with distinctive visible shell.
