Abell 2199 is a distant (~ 420 million light years) galaxy cluster, part of the Hercules galaxy supercluster. The brightest cluster galaxy (BCG) is by far NGC 6166, the elliptical cD type giant galaxy, with a hundred thousand light year long relativistic jet, related to the supermassive (~ 28 billion Solar masses !) black hole in the center.  Also noteworthy are the two large barred spiral galaxies, UGC10420 and UGC10404, on top of the image.

Aladin found almost 40 quasars in the field, the farthest one had redshift z=3.05 and light travel time was 11.6 Gyr. It is marked by an arrow left from the center.
