Above the horizon.  Circumpolar today
Alt: 28.02°   Az: 348.41°   Direction: North-North-West

NGC 4121 is a Elliptical Galaxy in the Draco constellation. NGC 4121 is situated close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere. Given its B magnitude of 14.1, NGC 4121 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

The image below is a photograph of NGC 4121 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).
