NGC 1804 - Open Cluster in Dorado

Below the horizon.  Never rises today
Alt: -68.27°   Az: 153.91°   Direction: South-South-East

NGC 1804 is a Open Cluster in the Dorado constellation. NGC 1804 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 11.87, NGC 1804 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 1804 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).
