IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus.
The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula.
The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago;the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years (WIKI)
This Northern object was VERY hard to image from 18 DEG South (Namibia)
During June There is a window of about an hour each night to image it.
