This dataset captures the Horsehead and Flame Nebulae region through 21.75 hours of integration collected between November 6 and December 14, 2025. The acquisition employed an Askar 71F telescope paired with a ZWO ASI 533MC Pro camera on an AM3 mount. The data comprises 265 frames through an Optolong L-Extreme HA-OIII 7nm narrowband filter and 170 frames through an Optolong L-Pro filter, all at 180-second exposures. This dual-filter approach provides both narrowband emission detail and broadband color information for the iconic dark nebula and its glowing companion. Licensed under CC BY-NC 4.0, the dataset permits copying, modification and redistribution for non-commercial purposes. Access requires a one-time purchase of approximately $17.90.
