This Ghost Nebula dataset comprises 33.95 hours of integration time captured between late May and late July 2025. The acquisition used an Askar 71F telescope paired with a ZWO ASI 533MC Pro camera on an AM3 mount. All 679 frames were shot through an Optolong L-Quad Enhance 2" filter at 180-second exposures, optimizing contrast for emission nebulae while managing light pollution. The data is released under a CC BY-NC 4.0 license, permitting free download, modification and redistribution for non-commercial purposes. This substantial integration time provides ample signal for detailed processing of the nebula's faint structures and subtle gradients across the field.
