IC5146 - The Cocoon Nebula

IC5146 - The Cocoon Nebula (also referred to as Caldwell 19 or Sh2-125). It is a reflection/emission nebula in the constellation Cygnus. IC5146 is the cluster of 9.5 mag stars in the nebula. which shines at magnitude +10.0. The cluster is about 4,000 light years away, and the central star that lights it was formed about 100,000 years ago. The nebula is about 15 light years in diameter. When viewing IC 5146, dark nebula Barnard 168 (B168) forms a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.

NGC2237 - Rosette Nebula in Monoceros

The Rosette Nebula (also known as Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) within the centre of the nebula is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
