This dataset captures Barnard 142 and 143, a pair of dark nebulae in Aquila, over nearly three weeks between mid-September and early October 2024. The total integration spans just under 15 hours, gathered with an ASI294MM Pro monochrome camera on a TS-130 APO refractor guided by an AM5 mount. The data comprises 222 luminance frames at 120 seconds each, supplemented by 85 blue, 70 green, and 72 red filtered exposures of identical duration using Antlia 1.25-inch filters. This combination allows detailed mapping of the dust lanes that define these catalogued opacity features against the background star field. The dataset is offered as a one-time purchase at approximately $19.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
