Description (Wikipedia)It is located in the northern part of the constellation, about 1.5 ° to WNW of the bright
star Deneb ; the most suitable period for its observation in the evening sky falls between the months of July and December and is considerably facilitated for observers located in the regions of the terrestrial
northern hemisphere .It is a circular
H II region of apparent dimensions of about 15 ', crossed by a dark band on its western side oriented north-south. The star responsible for its excitation is believed to be BD + 45 3216, a
double blue star of
spectral class O8V and an
apparent magnitude of 9.18;
[4] Estimates on the distance of this star provide a value of 1740
parsecs (about 5670
light years ),
[2] which would place Sh2-112 in a particularly rich region of
the Orion Arm and physically very close to the great nebulous system of
Cygnus X. The nebula is located in a star-
forming region which, according to the
Avedisova catalog , also includes some sources of
radio waves and the
molecular cloud [DBY94] 29, which has a
mass of 1880
M ⊙ ;
[5] however in a 1994 study a distance of 2100 parsecs is reported for this last cloud.
[6]Personal NoteThe name of the game is to find the best picture on Astrobin of the object take with similar equipment to yours and see how close you can get. For me this benchmark was a picture by Will Czaja. I think I came halfway, with more work needed on the brightness of the colors and the sharpness of the dark filaments.
