This dataset captures Sh2-124, a hydrogen emission nebula, through 28.67 hours of narrowband exposures collected between July and October 2025. The imaging campaign used a Sky-Watcher Esprit 120mm refractor paired with a ZWO ASI2600MM Pro monochrome camera on an AM5 mount. The data comprises 149 frames through Antlia 3nm H-alpha filters (300 seconds each), 102 OIII frames, and 93 SII frames, all at matching exposure durations. This tri-band narrowband approach enables Hubble palette processing or other false-color combinations that reveal ionization structures within the nebula. The dataset is available for approximately $19.90 as a one-time purchase under CC BY-NC 4.0 licensing, permitting copying, modification and redistribution for non-commercial purposes.
