North is to the left in this image. This field lies within the constellation of Cepheus. The dark nebula LDN 1228 (Lynds Dark Nebula) with its extended structure dominates in this image. This interstellar dust obstructs the view of visible wavelengths of  the background stars and objects. There are numerous cataloged objects associated with this dark matter - LDN1228 is the most prominent.  The brighter areas behind (apparently behind) the dark nebula and extending off the field to the left is known as LBN 550 (Lynds Bright Nebula). These objects , selected dark objects, and some of the bright stars are identified in the annotated image.  Horizontal FOV is 120'

Image center is approximately - Equatorial 2000: RA: 20h 59m 47s Dec: +7727'21"
