NGC 7658A - Lenticular Galaxy in Sculptor

Below the horizon.  Never rises today
Alt: -59.70°   Az: 81.74°   Direction: East

NGC 7658A is a Lenticular Galaxy in the Sculptor constellation. NGC 7658A is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 15.27, NGC 7658A 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 7658A 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).
