About this object

Cygnus is a glorious area of the summer sky full of many different types of objects. One could spend years just imaging different objects in this constellation. This particular image is of an interesting area in Cygnus that I imaged this spring into late summer. The image is roughly 1x2 deg and is located at RA 20 26 05 and DEC +45 47 30 or about 2.5 deg west of the bright star Deneb. The area is full of background emission nebulosity, mainly hydrogen (HII) but also some interesting streamers of doubly ionized oxygen (OIII) over on the right side which is part of the supernova remnant W63 (G082.2+05.3). On the annotated image there are several objects. Berkely 89, a small open cluster of stars is in the upper right. This cluster is around 3 arc minutes in size and 6654 light years distant. Towards the lower right is Lynds Dark Nebula (LDN) 913. Near the center, the brighter patch is the nebula designated as DSH J2026.0+4547 in the Simbad database. This nebula was the main interest in the image. I was contacted by several amateur astronomy researchers from India were looking to determine this nebula's true nature. They run an imaging team called team MoMi which stands for Mohan, Mishra which has had several discoveries. They asked me if I could image this object which I finally finished in early September. One of the researchers, Utkarsh Mishra and the MoMi team already have several discoveries under their belt. You can visit his website here:
