Sh2-115 and Sh2-116 in Cygnus

Sharpless 115 stands just north and west of Deneb, the alpha star of Cygnus constelation. This is faint but interesting in shape and shadows emission nebula that lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away. Shining with the light of ionized atoms of hydrogen, sulfur, and oxygen. In the picture I used combination of H L R G and B filters. The nebular glow is powered by hot stars in star cluster Berkeley 90. The cluster stars are likely only 100 million years old or so and are still embedded in Sharpless 115. But the stars' strong winds and radiation have cleared away much of their dusty, natal cloud.
