NGC 2431 - Barred Spiral Galaxy in Lynx

Above the horizon.  Circumpolar today
Alt: 38.02°   Az: 310.23°   Direction: North-West

NGC 2431 is a Barred Spiral Galaxy in the Lynx constellation. NGC 2431 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 14.3, NGC 2431 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

The image below is a photograph of NGC 2431 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).
