Image of the Month - February 2005
The globular cluster NGC 2419 is located in the constellation Lynx, roughly in the
direction of the galactic anticenter. The cluster is also known as the galactic Wanderer
because of it's distance of roughly 300.000 light years. While the cluster is gravitationally bound to our Galaxy, it's distance places it nearly
twice as far out as the Magellanic Clouds. The brightest stars in this cluster are
around magnitude 17, though NGC 2419 is also one of the intrinsically brightest globular clusters of the Milky Way - it would easily outshine the
famous Hercules cluster, M 13.

When Wolfgang Ries took this image of the cluster using a Starlight Express SXV-H9the CCD camera on the 0.3m f/6 Newtonian reflector of his
private observatory, he captured another wanderer: The faint trail of minor planet
(70308) 1999 RO135 (18.9mag) is visible north-west (upper-right) of the cluster, just north of the bright star. Ries, who is well-known for his
excellent images of the Sun, the Planets,
Star Clusters, Nebulae
and Galaxies, discovered his first
asteroids while taking images of the galaxy NGC 3628 in Leo in February 2004.
Since then, he has been credited with a dozen more discoveries.
