NGC 55 - Barred Spiral Galaxy in Sculptor

Below the horizon.  Never rises today
Alt: -25.88°   Az: 121.00°   Direction: East-South-East

NGC 55 is a Barred Spiral Galaxy in the Sculptor constellation. NGC 55 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 7.87, NGC 55 is visible with the help of a binocular with a 40-50mm aperture or a small telescope.

The image below is a photograph of NGC 55 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 0.9950x0.9950 degrees (59.70x59.70 arcmins).
