Blue Mountain Vista Observatory New RInggold PA
M65, or NGC 3623, is a mag 9.3 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 under the gravitational influence of its neighbors but M65
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.
