Still have issues with the weather ... rather poor seeing (my seeing is 'good' if it's under 3 seconds) and occasional clouds/fog. See the 8" version.

Contemporary Visual Observation(s) for NGC 4594

NGC 4594 = M104 = MCG -02-32-020 = UGCA 293 = Sombrero Galaxy = PGC 42407

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.
