SH2-119 - Clamshell Nebula

The Clamshell nebula, or Sharpless 119, is a large patch of emission in the summer constellation Cygnus and lies some 2200 light years away. It’s only 2-3 degrees away from the North American and Pelican Nebulae, so is often overlooked. The bright star is 68 Cygni, and is around magnitude 5 and is one of the stars responsible for ionizing the surrounding gas. Riddled throughout this complex are several brighter emission patches and dark nebulae with their own LBN and LDN designations.
