IC 443 is a Supernova Remnant in the Gemini constellation. IC 443 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 12, IC 443 is visible with the help of a telescope having an aperture of 8 inches (200mm) or more.

The image below is a photograph of IC 443 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 1.6667x1.6667 degrees (100.00x100.00 arcmins).
