NGC 2493 - Lenticular Galaxy in Lynx

Above the horizon.  Circumpolar today
Alt: 38.64°   Az: 71.91°   Direction: East-North-East

NGC 2493 is a Lenticular Galaxy in the Lynx constellation. NGC 2493 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 13.1, NGC 2493 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 2493 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).
