This dataset captures Sh2-140, a hydrogen emission nebula, through 18.07 hours of narrowband and broadband imaging collected between late October and late November 2024. The acquisition employed a TS-130 APO Refractor paired with an ASI294MM Pro monochrome camera on an AM5 mount. The data comprises 101 frames through a 3nm Antlia H-alpha filter at 300 seconds each, supplemented by 58 luminance frames and RGB color data totaling 135 frames at 180 seconds per exposure. This combination of deep narrowband hydrogen detail and shorter broadband channels provides flexibility for both scientific analysis and aesthetic processing. The dataset is available as a one-time purchase for approximately $16.90 under a CC BY-NC 4.0 license, permitting copying, modification and redistribution for non-commercial purposes.
