Leo Triplet
M65 (NGC 3623) is a spiral galaxy in Leo around 35 million light-years away and the brightest member of the Leo Triplet — a gravitationally bound group completed by M66 and the edge-on NGC 3628. Unlike its two companions, M65 has retained a remarkably undisturbed structure despite the group’s long history of mutual interaction, with well-defined spiral arms, a prominent dust lane along its southern edge, and very little active star formation. Its relative tidiness makes it something of an outlier in a trio otherwise showing clear signs of gravitational disruption. All three members fit within a single degree of sky, making the Leo Triplet one of the finest galaxy group targets for modest apertures.
