This dataset captures the Lion Nebula (Sh2-132) through 22.5 hours of total integration time, collected between October 28 and November 8, 2025. The acquisition employed an Askar 71F telescope paired with a ZWO ASI 533MC Pro camera on an AM3 mount. Two specialized narrowband filters were used: 235 frames through the Optolong L-Extreme HA-OIII 7nm filter and 215 frames through the Askar Color Magic D2 SII-OIII 6nm filter, all at 180-second exposures. This dual-filter approach isolates emission from ionized hydrogen, oxygen, and sulfur, revealing the nebula's complex ionization structure. The data is available as a free download under CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
