Description

This cluster is located in Ophiuchus. This a very rich area of the galaxy, lots of dust and gas. This cluster is relatively you g with some members not yet on the HR main sequence yet!

This exercise was an attempt to improve my stars. I have done a lot of reading and received some good advice and I think this image may show some improvement in that area.
