COMMENTS ON THE OBJECT:
Sh2-115 is an emission nebula visible in the constellation Cygnus.
It is located in the northern part of the constellation, about 2.5° northwest of the bright star Deneb; Noted in the 1959 catalog by astronomer Stewart Sharpless (as Sh2-115), the emission nebula lies along the edge of one of the giant molecular clouds in the outer Milky Way, about 7,500 light-years away. Hot stars in the Berkeley 90 star cluster power the nebular glow. The stars in the cluster are probably only about 100 million years old and are still embedded in Sharpless 115.
The small blue object is Sh2-116 or Abell 71. The nebula is also catalogued as PK 085 + 04.1, PN G084.9 + 04.4 and Sh 2- 116. Initially catalogued as a planetary nebula, the object is now recognized as a small HII emission spot. The best time to observe it in the evening sky is between July and December and is considerably easier for observers located in the northern hemisphere.
