The Horologium Supercluster (also known as Horologium-Reticulum Supercluster) is a massive supercluster, about 550 million light-years across and has a mass of 10¹⁷ solar masses. The nearest part of the supercluster is 700 million light-years away from us (mainly the clusters near the bottom of the picture) but the far end of it is 1.2 billion light-years (mainly the clusters at the top) in the constellations Horologium and Eridanus. The Horologium supercluster has about 5,000 galaxy groups (30,000 giant galaxies and 300,000 dwarf galaxies) and shows every galaxy brighter than magnitute 17. It includes the cluster Abell 3266.
