NGC 4218 - Intermediate Spiral Galaxy in Canes Venatici

Above the horizon.  Circumpolar today
Altitude: 72.1°   Azimuth: 270.0°   Direction: West

NGC 4218 is a Intermediate Spiral Galaxy in the Canes Venatici constellation. NGC 4218 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 4218 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 4218 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).
