Sombrero Galaxy 

Spitzer found that halo around the Sombrero Galaxy is larger and more massive than previously thought, indicative of a giant elliptical galaxy . The galaxy has an apparent magnitude of + 9.0, making it easily visible with amateur telescope, and it's considered by some authors to be the brightest galaxy within of 10 megaparsecs of the Milky Way. The large bulge, the central supermassive black hole, and the dust lane all attract the attention of professional astronomers
