Messier 93 or M93, also known as NGC 2447, is an open cluster in the constellation Puppis. It was discovered by Charles Messier then added to his catalogue of comet-like objects on March 20, 1781. Caroline Herschel, the younger sister of William Herschel, independently discovered M93 in 1783, thinking it had not yet been catalogued by Messier.
Facts about M93 by Keith Turnecliff
Some observers mention the cluster as having the shape of a starfish. With a fair-sized telescope, this is its appearance on a dull night,
but [a four-inch refractor] shows it as a typical star-studded galactic cluster.
The best time to observe M93 is during February / March.
