Object Info:

In the same field of view as M104, the Sombrero Nebula, there is a nice 11 star asterism, STAR 21, or Jaws, from Phil Harrington's "The Deep Sky, an Introduction. The asterism is called "Jaws" because it looks like a shark swimming in the Southern direction, the two brightest stars marking the head and mouth. The rest of the stars form the body, while the lonely star on the right is the tip of the dorsal fin. Easy the find. Just go to M104 or start from STAR 20, the Stargate (see log of Stargate in Corvus). Jaws lies about 1 degree northeast from Stargate. To the right, in a triangle of fainter stars, I just could detect M104. It was low to the light polluted horizon. I could not detect any detail.
