This interesting area is part of the great Orion molecular cloud complex ... and just about 2.6 degrees to the northeast of the M 78 area, and also forming an equilateral triangle with NGC 2112  ... see this color image of the area by Rogelio Bernal Andreo.

See this CDS list of objects within 15 minutes of the center of LDN 1622.

The glow to the west (right) is from the 4.75 visual magnitude star 56 Orion, which is just out of my field, and caused all manner of artifacts that I have (mostly) processed out the this image. Will probably try to re-image this area again with a different centering
