NGC 1342 is an open cluster of stars in the northern constellation of Perseus.[1] Alternatively, it is known as the Stingray Cluster,[4] or the Little Scorpion Cluster, due to a visual resemblance to the constellation Scorpius.[5]
NGC 1342 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.[6]
In 1962, Beverly Turner Lynds discovered LDN 1434, located nearby NGC 1342.[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.[7]
