      Description

      This image shows IC 5146, also known as the Cocoon Nebula. it is a combination emission and reflection nebula nearly 15 light-years wide and located 4,000 light-years away in the constellation of Cygnus. this image was taken using Luminance, Red, Green, Blue and H-alpha filters and classic newtonian setup. I used H-alpha filter in order to highlight faint hydrogen emission nebula in the background
