NGC 7822, also known as the Question Mark Nebula, is presented here as a 58.3-hour dataset captured between July 18 and August 24, 2026. The acquisition employed an AG12 Orion Optics telescope paired with a ZWO ASI 2600 MC Pro camera on a SkyWatcher EQ8 mount. The imaging strategy combined 280 frames through a Baader 6.5nm Ha filter at 300 seconds each, 154 frames through a Baader 8.5nm OIII filter at 600 seconds, and 186 unfiltered frames at 180 seconds. This multi-filter approach captures both ionized hydrogen and oxygen emissions alongside broadband luminance data. The dataset is offered under a CC0 1.0 Universal license, placing it in the public domain with no copyright restrictions. Access is available through a one-time purchase of approximately $23.90, providing calibrated sub-exposures suitable for custom processing workflows.
