IC 2118 is a very faint
reflection nebula illuminated by Rigel, which is about three degrees to its east. When
viewed at an orientation 90 degrees counterclockwise, it resembles an elongated face in
profile, with the brightest portions forming the "chin" and "nose,"
giving rise to its informal name of the "Witch Head Nebula."

Technical Notes: Individual exposures were dithered using CCDAutoPilot2 and then sigma combined. The RGB image was created in
Registar 1.0. Reduce Noise and Gaussian Blur were applied to the RGB image and the
luminance image. Glare from the zero-magnitude star Rigel created the artifact at the
bottom of the image, while glare from third-magnitude Cursa created the artifact on the
left side of the image.
