NGC 4004B is a Elliptical/Spiral Galaxy in the Coma Berenices constellation. NGC 4004B is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 15.2, NGC 4004B 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 4004B 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).
