NGC 2183 is a HII Ionized region in the Monoceros constellation. NGC 2183 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 15.15, NGC 2183 is visible with the help of a telescope having an aperture of 20 inches (500mm) or more.

The image below is a photograph of NGC 2183 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 0.4000x0.4000 degrees (24.00x24.00 arcmins).
