IC 10 - Irregular Galaxy in Cassiopeia

Above the horizon.  Circumpolar today
Alt: 75.89°   Az: 312.37°   Direction: North-West

IC 10 is a Irregular Galaxy in the Cassiopeia constellation. IC 10 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 9.5, IC 10 is visible with the help of a binocular with a 80mm aperture or a small telescope.

The image below is a photograph of IC 10 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).
