NGC 2264 The Cone Nebula


The Cone Nebula is about 2,700 light-years away from Earth and approximately 7 light-years tall or long depending on how you look at it. The Cone Nebula is an HA (Hydrogen Alpha) region in the constellation of Monoceros. The Cone Nebula and the surrounding Christmas Tree Cluster were discovered by William Herschel in 1785.

The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster which in most catalogs it refers to both objects and not just the Cone 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 the brightest star of NGC 2264.

This image was taken in the month of January 2013 and has become one of the best examples in the use of the Hyperion 12.5 scope, the stars are not distorted as with the use of the Meade 14” which causes distortion of the stars as you view the image from the center out to the edges. The advantage is not only round stars from edge to edge but also the image does not need to be cropped.
