Image Data

Designation M 104,  Sombrero Galaxy,  NGC 4594,  Bennett 52
Object type Spiral galaxy
Coordinates 12h40m,  - 11d39'
Constellation Virgo (Vir)
Description Called the Sombrero Galaxy because of its shape, this bright near-edge-on spiral lies 50 million lightyears away towards the Virgo cluster of galaxies, but very much nearer to us. M104 features a structured dust lane, a very bright core, well defined spiral arms and an unusually pronounced halo containing an extended globular cluster system. It was not listed in the first published Messier catalog.  Charles Messier added it by hand in his personal copy after identifying it as a 'very faint nebula' in May 1781.

There is also a close-up image taken with a 14.5" Ritchey-Chretien telescope.
