Open Cluster M48

M48(NGC 2548) is an open cluster in the Hydra constellation. It was discovered by Charles Messier in 1771. There is actually no cluster in the position indicated by Messier. The value that he gave for the right ascension matches that of NGC 2548, however, his declination is off by five degrees therefore credit for discovery is sometimes given instead to Caroline Herschel in 1783
