IC 4900 - Spiral Galaxy in Telescopium
IC 4900 is a Spiral Galaxy in the Telescopium constellation. IC 4900 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 16.16, IC 4900 is visible only through long exposure photography.
The image below is a photograph of IC 4900 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).
