Astrometry.net

I compiled the code found at http://www.astrometry.net/use.html on my Fedora 11 box (a VM really, hosted by VPSLink) in Boston. A couple edits to a couple makefiles, a bunch of yum installs for devel RPMs and I was off.

I fed it a test that it came with, and voila:

Your field contains:
 Part of the constellation Draco (Dra)
 Part of the constellation Ursa Major (UMa)

How cool is that? It also writes out a FITS file, and some PNGs which show the constellations in there, or any other object.
