IC 4808 - Spiral Galaxy in Corona Australis

Below the horizon. Never rises today

Alt: -83.18° Az: 333.70° Direction: North-North-West

IC 4808 is a Spiral Galaxy in the Corona Australis constellation. IC 4808 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 13.23, IC 4808 is visible with the help of a telescope having an aperture of 10 inches (250mm) or more.

The image below is a photograph of IC 4808 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).
