IC 907 - Spiral Galaxy in Ursa Major

Above the horizon.  Circumpolar today
Altitude: 47.9°   Azimuth: 298.2°   Direction: West-North-West

IC 907 is a Spiral Galaxy in the Ursa Major constellation. IC 907 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere.

The image below is a photograph of IC 907 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 0.5x0.5 degrees (30x30 arcmins).
