Sh2-115
Image Description and Details : Sh2-115 is a faint emission nebula in Cygnus, just about 1.5 degrees northwest of Deneb, the brightest star of the constellation. Inside Sh2-115 can be found the small open cluster Berkeley 90 . For long time Sh2-116 has been considerd a planetary nebula (even has its proper designation Abell 71, PK 085+04.1,or PN G084.9+04.4). But the recent studies describe it as a small patch of emission nebula Astrosib RC 20"+camera FLI Kepler 4040 cmos HOOrgb=19h06 no guiding The SkyX + Pixinsight + Photoshop From E-eye (Fregenal de la sierra, Spain)

The Alpha and Omega
Image Description and Details : This cosmic landscape depicts Sh2-115 and Abell 71, the first an emission nebula and the latter a planetary nebula. Or, in other words, the birth and the death of stars - hardly anything else more meaningfull to us.
