NGC 1342 is an open cluster of stars in the northern constellation of Perseus.[3] Alternatively, it is known as the Stingray Cluster,[4] This cluster was discovered by William Herschel on 28 December 1799. It is located in the south of the constellation, almost halfway between Algol (β Persei) and ζ Persei, away from the plane of the Milky Way. NGC 1342 has an apparent size of 17' and an apparent magnitude of 6.7, marginally visible by naked eye.[5] In 1994, Peña, J. H. and Peniche, R. estimated by the use of photometric data, that the age of the cluster is 400 million years.[6]
