NGC 1980 (also known as OCL 529, Collinder 72 and The Lost Jewel of Orion[6]) is a young open cluster associated with an emission nebula in the constellation Orion. It was discovered by William Herschel on 31 January 1786.[7] Its apparent size is 14 × 14 arc minutes and it is located around the star Iota Orionis on the southern tip of the Orion constellation.[4][8]
Herschel made his first observation of the cluster which was called WH V 31 on 31 January 1786, but he possibly observed it during his studies of double stars on 20 September 1783.[7]
