Description

Finally I took the time again for an open star cluster. This rarely shown cluster is located in constellation Ophiuchus and its age is estimated at 660 million years.

This cluster is nearly as large as the full moon, and contains 30 stars which make it shine at a total magnitude of 4.6 - the brightest star is of mag 7.6.

Hope you enjoy this sea of colorful stars :-)
