This dataset captures NGC 6523, the Lagoon Nebula, through 142 exposures totaling 11.83 hours of integration time. The data was collected between April 28 and May 23, 2025, using a Sky-Watcher Esprit 120mm refractor paired with a ZWO ASI2600MM Pro monochrome camera on an AM5 mount. The acquisition includes 61 luminance frames at 300 seconds each, complemented by 25 green, 33 blue, and 23 red channel frames, all through Antlia 2.00" filters at matching five-minute exposures. This emission nebula in Sagittarius offers rich hydrogen-alpha structure and dust lanes suitable for narrowband or LRGB processing. The files are available as a one-time purchase for approximately $7.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
