IC 2118
The Witch's Head Nebula

Combination of 15, 3 minute exposures using red, green and blue filters.
SBIG STL-1001E CCD. 5" f/5 refractor at prime focus.

IC 2118 is a large but faint reflection nebula in Eridanus, situated about 3 degrees west of the bright star Rigel, which is believed to be the source of illumination. It is a very difficult object for visual observation, and I am yet to succeed in seeing it with scopes of up to 10", despite very dark skies.
