The slightly more distant S0 or "early" Sa galaxy NGC 3593 is probably another member of the group, not in out image.
Our image was obtained by the German amateur Michael Weiland of the Interessengemeinschaft Astronomie at the University of Constance.
The table below lists some data for the M66 group members:
