IC 4100 - Spiral Galaxy in Canes Venatici
IC 4100 is a Spiral Galaxy in the Canes Venatici constellation. IC 4100 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 15.1, IC 4100 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 4100 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).
