Beschreibung:

NGC 2419 is an unusual globular cluster because it is so far away. It's out there orbiting the Milky Way beyond the Magellanic Clouds. It's also a great fit on Hubble's detectors because of its distance and large size, which is double great because there is a robust set of data in the archive, which made filling the chip gap rather trivial. Its nickname, Intergalactic Wanderer, is somewhat of a misnomer because it is orbiting rather than wandering (read the wiki article) but I think it's a great name and gives the cluster some character.

Make sure you do view larger version of the image because for some reason the interpolation Flickr uses for the photostream display is awful for denser star fields such as this one.

Data primarily came from this proposal: UVIS Photometric Zero Points

North is NOT up. It is 44° counter-clockwise from up.
