NGC 6984 - Spiral Galaxy in Indus

Below the horizon.  Never rises today
Alt: -60.11°   Az: 249.79°   Direction: West-South-West

NGC 6984 is a Spiral Galaxy in the Indus constellation. NGC 6984 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 12.65, NGC 6984 is visible with the help of a telescope having an aperture of 10 inches (250mm) or more.

The image below is a photograph of NGC 6984 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).
