This dataset captures NGC 6992, the Eastern Veil Nebula, a prominent supernova remnant in Cygnus. The data comprises 45 frames of 300 seconds each through an Optolong L-Quad Enhance 2" filter, totaling 3.75 hours of integration time. Acquisition took place over two nights in July 2025 using a Tecnosky OWL 90/540 refractor stopped down to 432mm focal length, paired with a PlayerOne Artemis C PRO camera on a Celestron CGX mount. The narrowband-optimized filter enhances emission from hydrogen-alpha and oxygen-III wavelengths, ideal for revealing the delicate filamentary structure of this ancient stellar explosion. The dataset is available as a one-time purchase for approximately $7.90 under a CC BY-NC 4.0 license, permitting copying, modification and redistribution for non-commercial purposes.
