IC2118 is an extraordinary faint reflection nebula distributed just west of Rigel, beta Ori.
The nebula is reflecting the light of Rigel,
but IC2118 belongs to a neighbored constellation of Eridanus.

The nebula has a shape of like a crescent with a length of about 3 degrees in north-south direction.
And IC2118 associates the face of aged-witch with its chin turned-up, so the nebula has a comical nickname of "The witch's face".
