The Sombrero Galaxy

This is the Sobrero galaxy M104 in Virgo as observed from my roof observatory in Germany in January 2009.
If you look at the bottom of the negative photo below you will notice two very faint objects, i.e. two galaxies called USNOA2-0750-07913859 and USNOA2-0750-07913885, categorized as stars in the USNO-A2.0 catalogue. They weren't recognised as galaxies before Hubble took a high resolution picture of M104's neighbourhood. Both galaxies are quite small (~14 arcseconds together) and faint (18th magnitude).
