Notes |
Sh2-115 is a faint emission nebula located in the constellation Cygnus. The small open star cluster in this is known as Berkeley 90. Sh2-116,also known as Abell 71 is a small, round shaped nebula. Abell 71 has a really weird history. First it was catalogued in 1955 by G.O. Abell as a planetary nebula and then someone decided it was an emission nebula but then people have realised it is actually an old, but true PN. |
