North is up in this image.  This image shows a region of interstellar material and dust illuminated by nearby stars as well as dark nebulae of dust blocking the light from background stars. The illuminated dust structure is LBN 762; the dark nebulae are various PGCC cold clouds.   There are several background galaxies in the image - some of which are visible through the dust of the nebula. These objects and some of the brighter stars are identified in the annotated image. Horizontal FOV is approximately 88 arc minutes. Full size image scale is 1.56 arcsec/pix.

Image center is approximately - Equatorial 2000: RA: 02h 59m 32s Dec: +1721'21"
