NGC 2264 was christened "The Christmas Tree"
by L.S. Copeland. It is a scattered cluster of about twenty bright stars
and measures about 30' in length - well suited to imaging with the shorter
focal length of the Televue Ranger.
The brightest star at the "trunk" of
the Xmas Tree is the fifth mag. S Monocerotis which is slightly variable.
At the top of the tree, running to the south of the mag 7 star lies the
famous "Cone Nebula" which is a dark nebula stretching for a distance
of six light years. This is an elusive object which only just started to
reveal itself after adding 14 x 40 sec exposures. It can be seen as the
large dark finger protuding downwards in the right hand image South lies
to the top in both images. The whole area is very rich in nebulosity.
