IC 4951 - Barred Spiral Galaxy in Pavo

Below the horizon.  Never rises today
Alt: -32.82°   Az: 209.16°   Direction: South-South-West

IC 4951 is a Barred Spiral Galaxy in the Pavo constellation. IC 4951 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 13.84, IC 4951 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

The image below is a photograph of IC 4951 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).
