Name:  NGC 2264 - Cone Nebula / Christmas Tree Cluster

The Cone Nebula is an H II region in the constellation of Monoceros.  The nebula is located about 2,600 light-years away from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC 2264 in the New General Catalogue refers to both objects and not the nebula alone.

The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264. The faint nebula is approximately seven light-years long, and is 2,700 light-years away from Earth.

The nebula is sometimes referred to as the Jesus Christ Nebula because of its resemblance to Jesus with his hands in a prayer position

This image was captured in conditions of bad sky glow caused by high clouds and bush fire haze.  Extracting the detail under these conditions is not without it's costs.  I will need to add more data to this image when conditions are better.
