Steve's Notes
=====
NGC 3660
48" (5/12/12): fairly bright, large, oval 5:4 WNW-ESE, ~2.5'x2.0', well concentrated with a bright, elongated core that seems to contains a brighter bar. The outer halo fades out gradually and increases in size with averted vision. 2MASX J11231643-0840067 (Ring Galaxy) lies 4' W and 2MASX J11234820-0841218 is 4.4' SE.
18" (3/19/04): fairly faint, fairly large, round, ~2' diameter with averted vision, broad concentration but then suddenly increases to a small nucleus. A faint star is off the west edge 1' from center. A trio of mag 10-12 stars follows by ~5'. Located 19' NE of mag 6.9 HD 98853.
