Steve's Notes

===== NGC 3511 48" (4/18/15): at 488x; very bright, very large, elongated 3:1 WSW-ENE, 5'x1.5'. Well concentrated with a large bright oval core that gradually increases to a small bright nucleus and stellar pip. The region surrounding the core is mottled, due to slightly brighter regions and dust patches. An ill defined broad spiral arm is on the west side of galaxy, curving from north to south. A mag 14 star, 2.0' SW of center, is barely off the southwest end of this arm. A bright patch is 1' SW of center (not part of the arm), and just to its north is a relatively large darker (dust) region. A second broad arm arc is visible at the east end of the galaxy making a sharp curve clockwise, and passing just inside a mag 13 star at the eastern tip. NGC 3513 lies 11' SE. 17.5" (4/1/95): fairly bright, large, very elongated 3:1 WSW-ENE, 4.0'x1.4'. Broad concentration to a larger brighter core. Bracketed by a mag 13 star at the ENE end and a mag 14 star at the WSW tip. Forms a pair with NGC 3513 10.8' SE. A mag 9.5 star (SAO 179479) is 5' S, roughly midway between the galaxies.
