Globular clusters are among the oldest structures in our galaxy. In these densely packed, spherical swarms, hundreds of thousands to millions of stars crowd together in a small space, so dense at the core that even large telescopes struggle to resolve them. They orbit the Milky Way in a vast halo and date back to the early universe. Magnificent examples like the Hercules Cluster, M13, are among the most striking targets of the summer sky. Photographically, the appeal lies in the transition from the bright, compact core to the scattered outer stars – resolving it cleanly without overexposing the centre is the real art. Globular clusters are bright enough for shorter exposures but benefit greatly from good seeing and precise tracking, so the individual stars stay crisp. This page gathers every globular cluster I have photographed so far. Click into any object to learn more about it and see all the astrophoto posts it appears in.
