NGC 7822, also known as the Question Mark Nebula, is presented here as a comprehensive dataset totaling nearly 38 hours of integration time. The data was collected over ten nights from September 2 to September 12, 2025, using an ASkar PHQ 151 telescope paired with a ZWO ASI2600MM Pro camera on an Ioptron HAE69 mount. The acquisition combines narrowband and broadband imaging: 149 frames through Antlia 3nm H-alpha (300 seconds each), 144 frames in OIII, and 134 frames in SII, supplemented by 24 frames each in Red, Green, and Blue filters at 120-second exposures. This dual approach enables both traditional narrowband palette processing and natural color renditions. The dataset is offered as a free download under CC BY-NC 4.0, permitting copying, modification, and non-commercial redistribution.
