32 Cygni is a binary star system (32 Cygni A and B). The orbital plane of the two stars is almost exactly aligned to the line of sight of the earth, which is why the system cannot be recognized optically as two stars. The emission nebula lies in the constellation of Cygnus, a dense star region of the Milky Way.
This field is also represented in the DWB catalogue - the lighter filaments of LBN 331 have the DWB designations DWB 179, 178, 177, 172, 171 (from left to right). 32 Cygni is at a distance to Earth of about 1,100 to 1,174 light years.
