This dataset captures SH2-290, also known as Abell 31, a planetary nebula imaged over nearly two months from early February through late March 2026. The collection comprises 34.75 hours of total integration time gathered with a Sky-Watcher Esprit 120mm refractor and ZWO ASI2600MM Pro camera on an AM5 mount. Narrowband imaging employed Antlia 3nm filters: 228 five-minute H-alpha exposures and 189 five-minute OIII exposures, isolating the nebula's ionized hydrogen and oxygen emissions. The data is offered as a one-time purchase at approximately $22.90 under a CC BY-NC 4.0 license, permitting copying, modification and redistribution for non-commercial purposes. This substantial integration time in dual narrowband channels provides robust signal for revealing the faint, extended structure of this evolved stellar remnant.
