- Description: IC5146 - The Cocoon Nebula in Cygnus. This shot was taken from home in
Calgary under Bortle 8-9 skies. (bad ones) This filter poked through light pollution just fine
allowing the capture of faint hydrogen light. This makes the dark nebula almost float against the
background nebulosity in Cygnus.
Also known as Caldwell 19, Sh2-125. The dark nebulosity is
known as Barnard 168 or The Caterpillar Nebula.
