Description

NGC 7789 is a beautiful, dense open cluster in the constellation Cassiopeia. It was discovered by Caroline Herschel, sister of William Herschel, in 1783. It lies at a distance of 7,600 light years from Earth. Observers of this cluster are greatly benefited by using a large telescope, as it is fainter than some of the more well-known clusters.
