NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually.
The star cluster is embedded in the nebula that spans some 110 light-years. The stars of NGC 7380 have emerged from this star forming region in the last 5 million years or so, making it a relatively young cluster.
