M65, or NGC 3623, is a mag 9.3 (visual) galaxy in Leo, part of the triplett with M66 and NGC 3628. It is estimated at 35 million light years distance.
It is close to and thus under the gravitational influence of its neighbors but M65 looks like a very "normal" Sa type spiral shows little influence. It has a prominent central lens and tightly wound spiral arms, plus a prominent dust lane marking the facing edge. The luminous disk is dominated by a smooth old stellar population. Near the lane, some knots are visible, which may be associated with star forming regions. The lane may hide regions of star formation usually associated with such features in spiral galaxies.
