- 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.
Although the scythe isn’t pre-eminent among the weapons of war, anyone who has been on the wrong end of, say, a peasants’ revolt will know that in skilled hands it is fearsome.
