Text taken from http://en.wikipedia.org/wiki/IC_5146:

The Cocoon Nebula, is a reflection/emission nebula and Caldwell object in the constellation Cygnus.

IC 5146 is a star cluster and the nebula is Sh2-125. It shines at magnitude +10 or even +7.2 according to other sources. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39.

The cluster is about 4,000 light years away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equavalent to a span of 15 light years.

When viewing IC 5146, dark nebula Barnard 168 is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.
