Near the Corvus-Virgo border lies M 104, the Sombrero-galaxy, a spiral galaxy that was discovered by Mechain in 1781. M 104 is a magnitude 8 galaxy, with a diameter of 8'x4'. Its surface brightness is 11, so it is a relatively bright galaxy. I was astonished how easily I could detect and observe it with direct vision using my 8-inch telescope, especially from my own backyard, where the southern sky is completely light polluted.
I used two fine asterism from Phil Harrington's book "The Deepsky, an introduction" to locate M 104. The asterisms are called Stargate (Harrington STAR 20) and Jaws (Harrington STAR 21), and I can tell you that together with M 104 these two asterisms form a splendid trio of deepsky objects that are easy to find, even for un-experienced observers.
Start at Corvus (the Raven), a distinct trapezoid of bright 3rd magnitude stars southwest of Virgo. Locate Delta Corvi and Eta Corvi, a pair of stars at the north-eastern corner of Corvus. Centre your finder scope on Eta Corvi. From there go north for about 3 degrees. You will find a triangle of stars in your finder scope, again pointing in north-eastern direction, at two fainter stars, which stand closely together. These two stars are part of Harrington's STAR 20, Stargate.
