NGC 2264 (Christmas Tree Cluster and Cone Nebula), Sh2-273 (Foxfur Nebula)
This is amazing region in the constellation of Monoceros, which includes some objects of different kind. NGC 2264 is a designation number that identifies two objects as a single object: the Cone Nebula and the Christmas Tree Cluster. The last is a young galactic cluster of stars in the Monoceros OB 1 association. Brightest members of the cluster resemble a "Christmas Tree". At its base is the variable star S Mon and at its top is the Cone Nebula - a conical shaped pillar of dust and gas. The part of the cloud near S Monocerotis has been designated as Sh2-273 and was nicknamed the "Foxfur" nebula due to its resemblance to a fox. This is a Ha_RGB combination. Other versions of this region are also available.
The subframes of this image were acquired in a long period of time (between November 2012 and January 2013) Since in begin of December I had to rotate slightly the camera (in order to improve the balance), the orientation of the subs are different. This explains the double star spikes.
