IC 5146   The Cocoon Nebula

IC 5146 The Cocoon Nebula is a reflection emission nebula in the constellation Cygnus. It is located near the naked-eye star Pi Cygni, the open cluster in Lacerta, and the bright open cluster M39. The cluster is about 4,000 light years away from Earth, and is about 15 light years across and the central star that lights the Cocoon was formed about 100,000 years ago. When viewing the Cocoon at this wide angle, the dark nebula Barnard 168, for me, is a huge part of the experience; it forms the dark lanes that surround the Cocoon and etends southward forming what looks like a trail behind the Cocoon.

This image was taken in the middle of October 2009 at  a dark sky site that has become a favorite spot for clear and dark skies. The image was taken not for its framing of the Cocoon itself but to capture the trailing effect that the dark nebula Barnard 168 gave to the image.

This image was taken in October of 2009
