Sharpless 112

Sh2-112

Sh2-112, listed in the Sharpless Catalog, is a relatively small emission nebula located about one degree from the bright star Deneb in the constellation Cygnus the Swan.  It lies approximately 5000 light years from the Earth.  The object seems to be rarely imaged by amateurs; however, it is, in my opinion, a worthy and interesting object.  The dust bands and bright emission regions make for a striking portrait.

The image above is known as a mapped, or false, color image and was acquired using narrowband filters.  It was assembled using the standard Hubble palette with SII mapped to Red, Ha mapped to Green and OIII mapped to Blue.
