This dataset captures NGC 7635, commonly known as the Bubble Nebula, through 11.58 hours of total integration time collected between August 16 and 18, 2025. The imaging session employed a Radian 75MM telescope paired with a ZWO ASI 533MC Pro camera on an AM5 mount. Data acquisition utilized dual narrowband filters: 84 frames of 300 seconds each through the Askar Duo-Narrowband D1 (Ha+OIII) filter, and 55 frames of 300 seconds each through the D2 (Sii+OIII) filter. This combination of hydrogen-alpha, oxygen-III, and sulfur-II data enables detailed mapping of the nebula's ionized gas structures. The dataset is available as a free download under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
