NGC 6164, known as the Dragon's Egg Nebula, appears in this narrowband hydrogen-alpha dataset captured on 8 May 2026. The acquisition comprises 360 frames at 40 seconds each through an Antlia 3nm H-alpha filter, totaling four hours of integration time. Equipment included a Sky-Watcher Quattro 250P telescope (10-inch aperture) paired with a Toupteck 2600MM monochrome camera on an HEQ5 pro mount. This emission nebula surrounds a massive Wolf-Rayet star that has shed its outer layers, creating the distinctive bipolar structure visible in hydrogen-alpha wavelengths. The dataset is released under CC0 1.0 Universal license, making it freely downloadable with no copyright restrictions for calibration, research, or processing experiments.
