Steve's Notes

===== NGC 4594 48" (2/20/12, 4/5/13): stunning view of the jet-black super high-contrast dust lane at 375x. The fainter section of the galaxy south of the dust lane was quite prominent and nearly as extensive as the northern half and the central bulge region was noticeably thicker in proportion to the major axis than views in smaller scopes. I also clearly noticed that although the dust lane was very flat in the central region (oriented precisely E-W), it bends slightly north and widens just a bit on both the east and west ends of the disc, giving it a slightly warped appearance. 48" (5/5/16): LEDA 962963 is just 8' SW of the center of M104, with both galaxies fitting in the same eyepiece field. It was easily seen as a fairly faint (V = 15.6, B = 16.4), small glow, slightly elongated NNW-SSE, 18"x14", slightly brighter nucleus. Situated 1.3' SE of a mag 10.4 star. 17.5" (3/12/94): 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 nonsymmetric sections. The prominent section of the core is just north of the dark lane. Overall, the galaxy is brighter and much more extensive to the north of the lane. The portion of the core and halo south of the dust lane is much fainter, smaller and unconcentrated. A mag 10 star lies 4' WSW. 13.1" (4/24/82): very bright, large, very elongated, arms long and thin. A prominent dark lane is visible along the length of the galaxy. Only a faint glow is visible to the south of the dust lane. 15x50mm binoculars (6/19/08 and 4/6/13): easily visible in binoculars as a elongated glow with brighter center.
