NGC 2264, the "Cone Nebula"
HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
The Cone Nebula is an Hydrogen emission region in the constellation Monoceros. Nebula is located about 2600 light years away from Earth. The cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. Note, NGC 2264 refers to both objects, not the nebula alone.
I have shot this object and the Rosette Nebula as a mosaic at Spring 2009, image can be found here:
The Cone Nebula area can be seen at the Left side.
