This dataset captures the Andromeda Galaxy (NGC 224, also known as M31) through 40 frames taken with an Optolong L-Enhance filter, each exposed for 300 seconds. The total integration time reaches 3.33 hours, all acquired on 2025-11-30. The imaging train consisted of a Redcat 51 telescope paired with a ZWO ASI585MC Air camera, mounted on a Sky-Watcher Star Adventurer GTI. The L-Enhance filter selectively passes hydrogen-alpha and oxygen-III wavelengths while suppressing light pollution, making it well-suited for capturing emission nebulae within and around M31. This dataset is released under a CC0 1.0 Universal license and is available as a free download, allowing unrestricted use for calibration tests, processing experiments, or integration into larger mosaics of the Andromeda Galaxy region.
