NGC 6819, the Foxhead Cluster   HOME INDEX BACK NEXT

Open Cluster in Cygnus

This rich open cluster contains about 150 stars, and it lies about 7200 light years away.  The two brightest stars in this picture are magnitudes 6.2 and 6.8, respectively.  The cluster itself has a total visual magnitude of 7.3, so it should be easy to see with binoculars (although a telescope is needed to resolve its stars, which are all dimmer than magnitude 11).  Through my 18-inch telescope at 158x, the cluster does have an eerie resemblance to an animal’s head with pointy ears. 

Magnitude 7.3
Apparent Size 5'
