Bright Nebulae LBN 777 and LBN 775 are the featured catalog items in this image. LBN
777 is also known as the Vulture Nebula due to its shape and appearance. The
back of the vulture's head" is the dark nebula Barnard 207. It is also
cataloged (approximately) as LDN 1491, Dobashi 4288, and TGU H1144. Barnard 207
is a mild star forming region and was the subject of a 2017 paper discussing the
proto star IRAS 04016+2610. This proto star is barely noticeable in the large
image - its location is shown in the annotated
image. One of several conclusions of this paper is that Barnard 207 is
comprised of larger than usual dust particles. This image also has some notable
background galaxies (UGC 2931, 2946, 2961, and PGC 014374). These objects as well as some bright stars are identified in the
annotated
image.. Horizontal FOV is approximately 85' Image center is located approximately - Equatorial 2000: RA: 04h 04m 35.0s Dec: +26°20'00"
