NGC 2273B - Spiral Galaxy in Lynx

Above the horizon.  Circumpolar today
Alt: 34.34°   Az: 33.78°   Direction: North-East

NGC 2273B is a Spiral Galaxy in the Lynx constellation. NGC 2273B is situated close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere. Given its B magnitude of 14.1, NGC 2273B 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 2273B 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).
