This dataset captures the M81 galaxy group across 51 hours of integration time, spanning nearly ten months from April 2024 to February 2025. The primary target, NGC 3031 (Bode's Galaxy), was imaged alongside M82 and NGC 3077 using two refractor telescopes: a TS-130 APO and a Sky-Watcher Esprit 120mm, both mounted on AM5 and AM3 equatorial mounts. Data was collected with ASI294MM Pro and ZWO ASI2600MM Pro monochrome cameras through five filter channels. The luminance channel comprises 393 frames at 300 seconds each, while narrowband hydrogen-alpha data includes 88 frames at the same exposure length. RGB channels contribute 74 blue, 71 green, and 76 red frames at 180 seconds per exposure. The dataset is available for approximately $24.90 under a CC BY 4.0 license, permitting modification and redistribution with proper attribution.
