Alt: -39.49°   Az: 172.04°   Direction: South

IC 2103 is a Spiral Galaxy in the Mensa constellation. IC 2103 is situated close to the southern celestial pole and, as such, it is easilty visible for most part of the year from the southern hemisphere. Given its B magnitude of 14.66, IC 2103 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 2103 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).
