Below the horizon.  Never rises today
Alt: -74.19°   Az: 195.54°   Direction: South-South-West

IC 4585 is a Barred Spiral Galaxy in the Triangulum Australe constellation. IC 4585 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, IC 4585 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 4585 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).
