North is to the right.

This beautiful complex of reflection and dark nebulae is in the constellation Monoceros. The large blue reflection nebula is IC 447. To the right and seemingly connected by a dark nebula is IC 446. This blue reflection nebula also shows glowing yellow dust. Above are reflection nebula NGC 2245 and further up is NGC 2247. NGC 2245 is also showing strong yellow dust. At the upper left corner is the red glow of the nearby Cone Nebula.
