IC 2101 is a Galaxy in the Eridanus constellation. IC 2101 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 14.5, IC 2101 is visible with the help of a telescope having an aperture of 20 inches (500mm) or more.

The image below is a photograph of IC 2101 from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in the image is 0.5000x0.5000 degrees (30.00x30.00 arcmins).
