This region in the constellation Monoceros contains several interesting features. The cone nebula at the bottom left is a "dark nebula", a region of gas & dust obscuring our vision of what's behind it, but it is outlined by a large area of glowing hydrogen gas. The blue region towards the center represents the reflection of starlight off dust particles. The foxfur nebula is a variegated area to the right of the blue region -- it's easily visible on the enlarged image. When viewed upside down, the area between the cone and foxfur region resembles a Christmas tree.  The stars in the "tree" are part of the open cluster, NGC 2264.
