NGC 4901 - Elliptical Galaxy in Canes Venatici

Above the horizon.  Circumpolar today
Altitude: 46.3°   Azimuth: 293.0°   Direction: West-North-West

NGC 4901 is a Elliptical Galaxy in the Canes Venatici constellation. NGC 4901 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 15.5, NGC 4901 is visible only through long exposure photography.

The image below is a photograph of NGC 4901 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).
