Core of the great Coma-Virgo galaxy cluster, with the bright pair of elliptical Messier-catalogue galaxies M84 (right) and M86 (on the left) at upper right anchoring the arc of galaxies called Markarians Chain. At centre is the giant elliptical M87, famous for its large black hole. M89, a smaller elliptical, is to the left, and M90, a spiral galaxy, is above it. M58 is at lower left, and the pair of interacting galaxies called the Siamese Twins, NGC 4568, are at bottom left. Dozens of other NGC, IC and PGC galaxies down to 15th magnitude dot the field. Photographed in southern Alberta, Canada on 14 May 2023.
