Sh2-114, as listed in the Sharpless catalog, is a faint, little studied[1,2], nebula located in the constellation Cygnus the Swan[1]. It has a filamentous structure that resembles a supernova remnant[1] such as NGC 6979 (Pickering's Triangle) found in the more famous Veil Nebula. This, however, does not seem to be the case for Sh2-114 as no supernovae, or their remnants, have been detected in the area[1]. Sh2-114's complex and wispy structure is probably the result stellar winds emitted by very hot and massive stars that are interacting with interstellar magnetic fields[2]. The distance to the nebula does not seem to be firmly established, however; I found one reference noting a distance of between 3,520 and 4,175 light years the Earth[3]. Many people see objects and animals in the clouds of our earthly skies. The same is true for the clouds in the celestial sky. Some see, in this celestial vista, a dragon with wings soaring through the heavens and have named Sh2-114 the Flying Dragon Nebula. 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. The stars were overlaid with color data from a separate RGB filtered image. A HOO (near true color) version of Sh2-114 may be viewed here.
