A framing of the 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 Markarian's Chain. At centre is the giant elliptical M87, famous for its monster 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.

This is a stack of 20 x 6-minute exposures with the Astro-Tech 90CFT refractor and its Reducer for f/4.8 and only 480mm focal length, and the filter-modified Canon R at ISO 800, on the Astro-Physics Mach 1 mount autoguided with the MGENIII autoguider. Galaxies enhanced by a starless layer created with RC-Astro StarXTerminator, and with Detail Extractor filter in Nik Collection 6 Color EFX. Taken from home May 14-15, 2023.
