M104 Sombrero Galaxy
M104, the Sombrero Galaxy, is named for its appearance as a brimmed hat with the edge formed by the prominent dust lane.  This is a very photogenic object, and this image could have been much better.  A bright moon was out and M104 was also low in the light-polluted sky, yet this shot still came out okay.  We view this galaxy nearly edge-on since there's only a 6 degree tilt.  X-ray emissions show material falling into the compact core of the galaxy where a one-billion solar-mass resides.
