Discovered by:The cluster was originally discovered by William Herschel on October 16th of 1787.
When William's sister, Caroline, transcribed his coordinates she made a mistake and referenced a vacant part of the sky.
This was later given the designation of NGC 7234. John Herschel, William's son, rediscovered his father's cluster in September of 1829.
Noting the coordinates his aunt had recorded were in error, he recorded the cluster at its correct location and the cluster was later designated NGC 7235.
This has resulted in both designations referring to the same open cluster

Description: NGC 7235 (also historically designated as NGC 7234) is a young, sparse open star cluster located approximately 9,200 light-years away in the constellation Cepheus.
It is estimated to be roughly 11.8 million years old, it contains relatively bright, young stars and is a popular target for deep-sky astrophotographers
