Sh2-112, as listed in the Sharpless Catalog, is a relatively small emission nebula located in the constellation Cygnus the Swan about 1.5 degrees from the bright star Deneb. This bright nebula is excited to glow by a massive star catalogued BD+45 3216. This star lies approximately 2.1 kilo parsecs (6849 light years) from the Earth. It is the bright star on the lower eastern edge of the dark dust band that transvers the nebula from the north to south. The nebula is a stellar nursery containing a rich population of young stars with an average age of about 1 million years. The displayed Sh2-112 image is oriented with north to the top and east to the left.
The image above was assembled as a bi-color image using narrowband filters. Ha filtered data was mapped to Red and OIII data mapped to Green and Blue. Stars were overlaid with data from a separate RGB filtered image. This method produces a near true color image. A Hubble Palette (SHO) version of the image may be viewed here.
