Ptolemy Cluster Messier M7

Open starcluster Messier M7, Ptolemy Cluster, is located in constellation scorpius and is about 980 light years away from Earth. The cluster has been known already since 130AD and observed by the Greek astronomer Ptolemy. 

The open starcluster is the most southern Messier Object with an altitude op 3,5° above the southern horizon. So it's a real challenge to find it. It can only be seen with a perfect view on the southern horizon.
