NGC 1980 (also known as OCL 529, Collinder 72 and The Lost Jewel of Orion[4]) is a young open cluster associated with an emission nebula which is located in the constellation Orion. It was discovered by John Herschel on 31 November 1786.[5] Its size is 14.00 by 14.0 arc minutes and is located around the star Iota Orionis on the southern tip of the Orion Constellation.[3][6]

Even though Herschel made his first observation of the cluster which was called WH V 31 on 31 November 1786, but he possibly observed it during his studies of double stars on September 20, 1783.[5]
