This Jellyfish Nebula dataset contains 45.4 hours of narrowband imaging captured between February and March 2026 using a Redcat 51 telescope and ZWO ASI585MC Air camera on a Sky-Watcher EQ-AL55i Pro mount. The collection comprises 908 frames split between two specialized filters: 376 exposures through an Optolong L-Extreme HA-OIII 7nm filter and 532 frames using an Askar Color Magic D2 SII-OIII 6nm filter, all at 180 seconds each. This dual-filter approach captures emission from hydrogen, oxygen, and sulfur, enabling detailed mapping of the nebula's complex ionized gas structures. The data is available as a one-time purchase for roughly $17.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
