This dataset captures NGC 7635, the Bubble Nebula, through 22.9 hours of narrowband integration collected between late July and late September 2025. The imaging setup employed a Sky-Watcher Esprit 120mm refractor paired with a ZWO ASI2600MM Pro monochrome camera on an AM5 mount. Data comprises 108 frames in Antlia 3nm H-alpha at 300 seconds each, 85 frames in OIII, and 82 frames in SII, all using matched 2-inch narrowband filters. This tri-band approach enables flexible processing into Hubble Palette or other false-color mappings that reveal the nebula's ionized hydrogen shell and surrounding emission structures. The dataset is available as a one-time purchase at roughly $19.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
