North is to the right in this image.   The dark smudges across the center of this field  is from a dark nebula region. Predominate dark nebulae are LDN 989 and LDN 974, however, there are multiple items from the Dobashi and TGU catalogs. The more significant Dobashi and TGU items are shown in the annotated image. This field also includes two NGC open clusters in the  opposite upper corners - NGC 7062 and NGC 7067 (left to right). Finally, there are two bright nebulae from Bernes Bright Nebulosities in Opaque dust Clouds Catalog - [B77] 27 and [B77} 28. These objects  as well as some bright stars are identified in the annotated image..  Horizontal FOV is approximately 120'

Image center is located approximately - Equatorial 2000: RA: 21h 20m 22s Dec: +4708'20"
