AvdH Posted October 31, 2021 Share Posted October 31, 2021 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 also known as Collinder 470. 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 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. When viewing IC 5146, dark nebula Barnard 168 (B168) 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. 8 Quote Link to comment Share on other sites More sharing options...

Dmack1 Posted November 2, 2021 Share Posted November 2, 2021 I think thats one of the nicest Cocoons I've seen. Nice detail in the nebula itself, wonderful star colours and the dark neb standing out really well. Nicely done. Quote Link to comment Share on other sites More sharing options...
