IC 3909 - Spiral Galaxy in Canes Venatici

Above the horizon.  Circumpolar today
Altitude: 72.7°   Azimuth: 237.6°   Direction: West-South-West

IC 3909 is a Spiral Galaxy in the Canes Venatici constellation. IC 3909 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 16.64, IC 3909 is visible only through long exposure photography.

The image below is a photograph of IC 3909 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).
