Cocoon Nebula
About this celestial object
The Cocoon Nebula IC 5146 glows at the end of the dark cloud Barnard 168.
IC 5146 combines emission and reflection components; a narrow dark cloud leads to the nebula like a conduit.
The short total time and humid air limit depth, yet the characteristic form stands out.
At 250 mm and F/5, the image spans a broad environment in Cygnus.
