Cone Nebula - NGC 2264 - Monoceros

Object data: NGC 2264 (Monoceros) is a giant region of ionized gases some 10 degrees to the east of Betelgeuse (Orion). At the southern end is the fantastic Cone Nebula, an apt description for this mass of dark matter protruding into the bright star forming region around its apex. Immediately above, the bright 5th magnitude star, S Mon., forms the apex of the Christmas Tree Cluster which extends northwards outside this frame. A dozen or so stars form the nearly perfect outline of the tree. The Cone Nebula and the Christmas Tree Cluster were discovered by William Herschel in 1783 from his observatory in Bath, England (about 30 miles from my home location in Wiltshire)
