Additional Notes:
The diffuse Cone Nebula, so named because of its apparent shape, lies in the southern
part of NGC 2264, the northern part being the magnitude-3.9 Christmas Tree Cluster. It
is in the northern part of Monoceros, just north of the midpoint of a line from Procyon
to Betelgeuse.
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 (with an apparent length of 10 arcminutes), and is 2,700 light-years
away from Earth. [Wiki]
