Sharpless 116 (Abell 71 )

SH2-116 is a small nebula that is also known as Abell 71 and sits not from the bright star Deneb in Cygnus. This object was first classified as a planetary nebula but recent studies show it to be an HII region instead. This object is best imaged using a larger telescope because of its size and some of the nice structure it has. However, SH2-115 is right next to it and a larger field of view can easily pick up both of them. The nebula surrounding SH2-116 is indeed part of SH2-115.
