|Sharpless 2-112: Emission Nebula (Cygnus) RA: 20h 34.1m / DEC: +45° 38'.7|
Instrument: 10-inch Starfinder
What a gorgeous bit of nebulosity! Sharpless 2-112 is an emission nebula tucked away in northern Cygnus. Deneb lies just 1.3 degrees to the east-southeast. The sketch at left presents an 82X view in my 10-inch Starfinder Newtonian. An OIII filter was used to enhance contrast. 9.2 magnitude SAO 49801 is at the center of the field. Sh 2-112 ranges broadly toward the east over a 10'x12' area. The nebula shyly displays delicate filamentary structure to the eye. It's almost boxy in shape with brighter west and north sides. There's just a hint of nebulosity detatched west of Sh 2-112. I would love to observe this through a 15-inch or larger instrument. Twenty-three stars frame this portrait.
