NGC 7234 - Open Cluster in Cepheus

NGC 7234 is an open star cluster lying approximately 9200 light years away in the constellation of Cepheus. It was discovered by William Herschel in 1787. However, his sister made an error in recorded the coordinates, which referred to an empty region of the sky. John Herschel, William's son, discovered the error in 1829 and gave it the designation of NGC 7235. This makes the cluster unique in that it actually has two designations.
