IC 203 is a Galaxy in the Cetus constellation. IC 203 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 16.9, IC 203 is visible only through long exposure photography.

The image below is a photograph of IC 203 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).
