NGC 1245 is an open cluster in the constellation Perseus. It was discovered by William Herschel in 11 December 1786.[2] It is located 3° southwest of alpha Persei and can be spotted with 10x50 binoculars.[3] The cluster is nearly 1 billion years old.[4] NGC 1245 has about 200 members the brightest of which are of 12th magnitude.[5] The cluster shows evidence of mass segregation and it is possible that it has lost its lower mass members.[6] Lying at a distance of 3kpc, the cluster is estimated to be 27 light years across.[4]
