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 obtained using CCDAutoPilot2 and then sigma combined. The RGB image was created in Registar 1.0. A Gaussian Blur was applied to the RGB image and the luminance image. A copy of the RGB image was combined with the original using Soft Light to enhance color. Field curvature is present at the corners of the frame.
