This image shows you a dimmed Hα emission nebula lying at 10 degrees southeast of Deneb. The nebula looks like a filamentary circle with a diameter of a degree, identified as Sh2-113 and Sh2-114 at the southern and northern portions respectively. Although the shape resembles a supernova remnant but we have no evidences of any supernova explosions in this vicinity. It is considered that the nebulae are only part of outer ridge of the Cygnus vast nebulosity which forms the North American Nebula (NGC7000) at 10° northwest.
