Image of M104 (Sombrero Galaxy) acquired with the CHI-1 telescope. Used RGB-data from 2 one-click observations.
The Sombrero Galaxy (also known as M104 or NGC 4594) is a spiral galaxy in the constellation borders of Virgo and Corvus, being about 31.1 million light-years from our galaxy, within the local supercluster. It has a diameter of approximately 49,000 light-years, 30% the size of the Milky Way. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which is viewed almost edge-on. The dark dust lane and the bulge give this galaxy the appearance of a sombrero hat.
Total exposure time 60 minutes. 4 subs of 300s each with the RGB-filters.
