North is to the right in this image.   The main feature in this image is the dark nebula region of LDN 513 and LDN 519. This field  is located right on the edge of the Milky Way galactic disk. The star field is fairly dense and somewhat reddened due to the intervening dust in the galactic disk. In addition to LDN 531 and LDN 519, there are dark nebulae from the TGU and Dobashi catalogs in this field as well. These dark nebulae as well as some of the brighter stars are identified in the annotated image.. Horizontal FOV is 85'

Image center is located approximately - Equatorial 2000: RA: 18h 12m 02s Dec: -0135'46"
