Galaxy clusters are among the largest gravitationally bound structures in the Universe. They consist of dozens to thousands of galaxies held together by immense amounts of dark matter and hot intergalactic gas. Well-known examples include the Virgo Cluster and the Coma Cluster, alongside many smaller and more compact systems from the Abell, Hickson and NGC catalogues. Long-exposure astrophotography reveals not only countless member galaxies but often distant background galaxies as well, showcasing the extraordinary depth of the cosmos. Every galaxy cluster offers a unique glimpse into the large-scale structure of the Universe. This page gathers every galaxy cluster I have photographed so far. Click into any object to learn more about it and see all the astrophoto posts it appears in.
