Sh2-112 in SHOrgb

Sh2-112 is a visibly emitting nebula in the constellation of Cygnus.


It is located in the northern part of the constellation, about 1.5 ° to WNW of the brilliant star Deneb.


It is a circular H II region of apparent size of about 15', crossed by a dark band on its western side oriented in a north-south direction. It is believed that the star responsible for its excitation is BD+45 3216; estimates of the distance of this star provide a value of 1740 parsec (about 5670 light years), which would place so Sh2-112 in a region of the Orion Arm particularly rich and physically very close to the great nebulous system of Cygnus X.
