Details:
Messier 93 (M93, NGC 2447) is a nice open star cluster in constellation Puppis. As one of the last deepsky objects found by him personally, open cluster M93 was discovered by Charles Messier and cataloged by him on March 20, 1781. M93 is one of the smaller but bright open clusters, the stars forming a triangular shape. At least about 80 members appear scattered over its 22' apparent diameter, which is of the order of 20-25 light years linearly at its distance of about 3,600 light years. The brightest stars of M93 are blue giants, its age has been estimated as roughly 100 million years. (ref: http://www.messier.seds.org/)
