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: +47°08'20"
