This dataset captures M33, the Triangulum Galaxy (NGC 598), through 33.5 hours of total integration time collected between December 2024 and early February 2025. The imaging campaign employed an ASI294MM Pro monochrome camera paired with a TS-130 APO refractor on an AM5 mount. Data comprises 590 individual frames across five filters: 185 luminance exposures at 180 seconds each, plus red (104 frames), green (80 frames), and blue (100 frames) channel data at matching 180-second exposures. Narrowband hydrogen-alpha detail comes from 121 frames captured through an Antlia 3nm filter at 300 seconds per exposure. The complete calibrated dataset is available for one-time purchase at approximately $24.90 under a Creative Commons BY-NC 4.0 license, permitting copying, modification, and non-commercial redistribution while requiring attribution.
