This dataset captures Markarian's Chain across 31.3 hours of integration time, collected between 14 February and 24 March 2026. The acquisition consists of 626 frames at 180 seconds each through an Optolong L-Pro 2-inch filter, designed to reduce light pollution while preserving the natural colour information from the one-shot colour sensor. The imaging train pairs an Askar 71F telescope with a ZWO ASI 533MC Pro camera on an AM3 mount. Markarian's Chain is a striking arc of galaxies in the Virgo Cluster, including several Messier objects and NGC catalogue entries that trace a curved path across the sky. The dataset is available as a free download under a CC BY-NC 4.0 license, permitting copying, modification and redistribution for non-commercial purposes.
