Description

Imaged on nights of 2018-10-19, 2018-10-20, 2018-21-19, 2018-11-25, 2018-11-26.
The RGB were taken on the AG12+ASI1600MM at .70 asec/pix, the L on TV127is+ASI183MM at .75 asec/pix, and RGB on AG12+ASI183MM at .43 asec/pix. Using L from the TV NP127is refractor effectively eliminates the spikes from the AG12.

IC 5146 Cocoon Nebula is a reflection/emission nebula 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. It shines at magnitude +10.0. 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.
