Caroline’s Rose is an open star cluster about 8,000 light years (ly) from Earth in the constellation Cassiopeia and is about 1.6 billion years old, as evidenced by the preponderance of yellow/orange older stars – red giants. The main part of the cluster is about 50 ly across and covers about half a degree (30 arc-minutes) in the sky (about the same as our Moon).
The cluster was discovered by Caroline Herschel in the late 1700’s and is so named because of the interweaving lands of stars and voids suggesting a rose petal arrangement.

This is one of my most favorite clusters of stars to look at in the sky. The dark lanes just make it look so interesting and it does remind one of a rose in the stars.
Beautiful job processing Greg with great star colors.
