NGC 2301 is an open cluster of stars in the constellation of Monoceros.[3] It was discovered by German-English astronomer William Herschel in 1786. This formation is visible through 7x50 binoculars and it is considered the best open cluster for small telescopes in the constellation.[4] It is located 5° WNW of Delta Monocerotis and 2° SSE of 18 Monocerotis. The brightest star of the cluster is an orange G8 subgiant star of 8.0 magnitude, but it is possible that it is a foreground star. The cluster contains also blue giants. The brightest main sequence star is a B9 star with magnitude 9.1.[5]
