Sombrerocropdone.jpgSombrero galaxy1519 viewsThe Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 28 million light years from Earth. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero. Astronomers initially thought that the halo was small and light, indicative of a spiral galaxy. But Spitzer found that halo around the Sombrero Galaxy is larger and more massive than previously thought, indicative of a giant elliptical galaxy. [5] The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes. The large bulge, the central supermassive black hole, and the dust lane all attract the attention of professional astronomers.MartinMay 11, 2012

NGC1365crop.jpgNGC1365.419 viewsI did this galaxy with the ED80 to see how much detail i could get with a 80mm scope.
I could get more detail than expected.

NGC55done.jpgNGC55.450 viewsNGC 55 (also known as Caldwell 72) is a barred irregular galaxy located about 7 million light-years away in the constellation Sculptor. Along with its neighbor NGC 300, it is one the closest galaxies to the Local Group, probably lying between us and the Sculptor Group.
NGC 55 and the spiral galaxy NGC 300 have traditionally been identified as members of the Sculptor Group, a nearby group of galaxies in the constellation of the same name.
