NGC 4594 = M104 = MCG -02-32-020 = UGCA 293 = Sombrero Galaxy = PGC 42407 12 39 59.4 -11 37 23 V = 8.0; Size 8.7x3.5; SB = 11.6; PA = 89d 17.5": very bright, very large, elongated 3:1 E-W, 7.5'x2.5'. Very prominent dust lane along the entire length of the major axis and divides the core into two nonsymmetrical sections. The prominent section of the core is just N of the dark lane. Overall, the galaxy is brighter and much more extensive to the N of the lane. The portion of the core and halo S of the dust lane is much fainter, smaller and unconcentrated. A mag 10 star lies 4' WSW. 13": very bright, large, very elongated, arms long and thin. A dark lane is visible along the length of the galaxy. Only a faint glow is visible to the S of the dust lane. - by Steve Gottlieb
