NGC 1817

NGC 1817 is an open cluster of stars in the constellation Taurus. It was discovered by English astronomer William Herschel in February 1784. With an apparent magnitude of 7 and spanning 17 arc minutes across the sky, it is separated from the NGC 1807 cluster by just a few degrees. Indeed, the two may actually be parts of a single extended cluster.
