This dataset captures NGC 6888, the Crescent Nebula, through 36.3 hours of integration time spanning nearly two years from August 2023 to July 2025. The data combines narrowband and broadband imaging using an Askar PHQ107 telescope with a QHY268M camera on a ZWO AM5 mount. Narrowband coverage includes 57 frames of 5-minute H-alpha exposures, 106 frames of 5-minute SII exposures, and extensive OIII data totaling 331 frames across 2-minute, 3-minute, and 5-minute exposures. Broadband RGB channels add 467 frames with exposures ranging from 1 to 2 minutes per filter. All filters are Antlia 36mm models, with the narrowband filters featuring 3nm bandwidths for high contrast emission line imaging. The dataset is released under CC0 1.0 Universal, placing it in the public domain with no copyright restrictions. Access requires a one-time purchase of approximately $21.90.
