The Leo Triplet, also recognized as the M66 Group, comprises a compact cluster of galaxies located approximately 35 million light-years away in the Leo constellation. This group encompasses the spiral galaxies M65 (right), M66(left), and NGC 3628(top). The amazing thing is I'm actually seeing stars down to 16-17 magnitude from an inner city.  All processing done in Seestar. 363 x 10 Seconds from a single night on 05 May 2024.
