This dataset captures IC 5146, the Cocoon Nebula, through 28.4 hours of total integration time collected between July and September 2024. The imaging campaign employed a TS-130 APO Refractor with an ASI294MM Pro camera on an AM5 mount. The data comprises 743 individual frames across five filters: 364 luminance exposures at 120 seconds each, plus red, green, and blue channel data (102, 104, and 100 frames respectively, also at 120 seconds). Narrowband hydrogen-alpha detail comes from 73 five-minute exposures through an Antlia 3nm filter. All color filters are Antlia 1.25-inch models. The dataset is available as a one-time purchase for approximately $16.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
