IC 257 - Elliptical Galaxy in Perseus

Above the horizon.  Circumpolar today
Alt: 15.69°   Az: 330.27°   Direction: North-North-West

IC 257 is a Elliptical Galaxy in the Perseus constellation. IC 257 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 14.5, IC 257 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 257 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).
