Barnard's Loop detail and M78 nebula in Orion - Barnard's Loop detail and M78 nebula...

Barnard's Loop detail and M78 nebula in Orion - Barnard's Loop detail and M78 nebula in Orion - Barnard's Loop is a very low emission nebula, very large, that surrounds the great Orion nebula. Here, the brightest part of the Loop, with lower left the cluster of stars NGC 2112, and to the right the nebula by refexion M78. Also visible is a dark nebula LDN 1622 at the top left of the image. Barnard's Loop is an extremely faint emission nebula which is part of an amazing, even larger complex of nebulosity in the constellation of Orion. This photo shows only the brightest central portion of the loop which runs diagonally across the frame here from lower left to upper right. NGC 2112, a ninth magnitude open cluster 11 arc minutes in diameter and containing about 50 stars, is seen at lower left - center, and reflection nebulae M78 and NGC 2071 are at lower right. An interesting dark nebula, LDN 1622, lies at the upper left of the image, surrounded by very faint emission nebulosity, with a hint of reflection nebulosity on the outlying western edge
