NGC 846 - Barred Spiral Galaxy in Andromeda

Above the horizon.  Circumpolar today
Alt: 10.86°   Az: 24.68°   Direction: North-North-East

NGC 846 is a Barred Spiral Galaxy in the Andromeda constellation. NGC 846 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 13.2, NGC 846 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 846 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).
