NGC 2264, The Christmas Tree Cluster

Contributor: Dany Duprez

This detail cropped from the main image is centred on NGC 2264. The view is 1.48 across. The brightest star in the field is 15 Mon (V=4.7).
This cluster-nebula combination was discovered by William Herschel. The open cluster, later logged as Collinder 112, was found by him on the night of 18 January 1784. The associated nebulosity was only noted on 26 December 1785. Herschel recorded that 'some pretty bright stars 7' or 8' south-preceding 15th Monocerotis are involved in extremely faint milky nebulosity which loses itself imperceptibly.'
The famous Cone Nebula lies to the south of the cluster.
