SH2-112
SH2-112, also known as LBN 337, is a diffuse emission nebula located about 5,600 light-years away in the constellation of Cygnus. This is a circular region of HII with dark dust rifts that can be seen on the western side. The star responsible for its excitation is believed to be BD+45 3216, a double blue star of spectral class O8V with an apparent magnitude of 9.18. It is located in a portion of the Orion Spiral Arm that is noted for areas of rich star formation.
