Sh2-115 is a faint emission nebula annoted by S.Sharpless in 1959.
It is located in Cygnus about 7,500 light-years away, just 1 and 2 degrees northwest of Deneb, the brightest star of that constellation.

Sh2-116 or Abell 71 is the designation of the small round patch of emission nebulosity to the upper left of Sh2-115.
