Description

Messier 7 or M7, also designated NGC 6475 and sometimes known as the Ptolemy Cluster is an open cluster of stars in the constellation of Scorpius. The cluster is easily detectable with the naked eye, close to the "stinger" of Scorpius. With a declination of −34.8°, it is the southernmost Messier object.
Yet another practising day for star clusters.
