NGC 3769 - Spiral Galaxy in Ursa Major

Above the horizon.  Circumpolar today
Alt: 9.37°   Az: 4.09°   Direction: North

NGC 3769 is a Spiral Galaxy in the Ursa Major constellation. NGC 3769 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 11.7, NGC 3769 is visible with the help of a telescope having an aperture of 8 inches (200mm) or more.

The image below is a photograph of NGC 3769 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).
