View larger image

NGC 7789 is a very rich open cluster of about 900 stars. It was discovered by Caroline Herschel in 1783, and was subsequently included in the catalog of deep-sky objects compiled by her brother, William Herschel. Its nickname derives from the strings of stars that give the cluster the appearance of a rose. It is also sometimes called the White Rose Cluster. It is a fine view in just about any type of telescope.
