Below the horizon.  Never rises today
Alt: -65.60°   Az: 149.77°   Direction: South-South-East

NGC 2157 is a Globular Cluster in the Dorado constellation. NGC 2157 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 10.16, NGC 2157 is visible with the help of a binocular with a 80mm aperture or a small telescope.

The image below is a photograph of NGC 2157 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).
