Leo’s Triplet Galaxy Cluster

  • This group of galaxies is found about 35 million light-years away (unfathomably far away), in the constellation Leo, hence the name. The three galaxies are Messier 65 (top right), Messier 66 (bottom right) and NGC 3628, aka the Hamburger galaxy (left). With only 2.3 hours of integration time, I couldn't pull out too much detail, but I still enjoy the result, especially the galactic tidal stream around messier 66.
