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. |
