IC 1903 NED02 - Elliptical/Spiral Galaxy in Horologium

Below the horizon.  Never rises today
Alt: -28.95°   Az: 136.11°   Direction: South-East

IC 1903 NED02 is a Elliptical/Spiral Galaxy in the Horologium constellation. IC 1903 NED02 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 16.6, IC 1903 NED02 is visible only through long exposure photography.

The image below is a photograph of IC 1903 NED02 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).
