NGC 7690 - Spiral Galaxy in Phoenix

Below the horizon.  Never rises today
Alt: -54.35°   Az: 113.98°   Direction: East-South-East

NGC 7690 is a Spiral Galaxy in the Phoenix constellation. NGC 7690 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 12.01, NGC 7690 is visible with the help of a telescope having an aperture of 8 inches (200mm) or more.

The image below is a photograph of NGC 7690 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).
