North is to the right in this image. This field lies within the constellation of Taurus. This image contains dark nebulae and star forming within the larger structure known as the Taurus Molecular Cloud (TMC). A smaller section of the TMC is known as TMC-1 CP which is known as the area of Cyanopolyyne Peak. The TMC contains many complex organic compounds. The central reflection nebula is IC 2087 - it is surrounded by multiple dark nebulae that are well represented in the Dobashi Dark Cloud Catalog. On the left side of the image are two galaxy groups and several of the more prominent ones are seen in this image as background galaxies. Also in the lower left corner is the little planetary nebula PN H 3-29. These objects , background galaxies, and some of the bright stars are identified in the annotated image. Horizontal FOV is 120'
Image center is approximately - Equatorial 2000: RA: 04h 40m 06s Dec: +25°39'26"
