This dataset captures the Cone Nebula and Christmas Tree Cluster region through 37.7 hours of total integration time, acquired between late December 2025 and early February 2026. The imaging train consisted of an Askar 71F telescope paired with a ZWO 533MC Pro camera on an AM3 mount. Data collection employed three filter configurations: 350 frames through an Optolong L-Extreme HA-OIII 7nm filter at 180 seconds each, 350 frames using an Askar Color Magic D2 SII-OIII 6nm filter at the same exposure length, and 54 broadband frames through an Optolong L-Pro filter, also at 180 seconds per frame. The dataset is offered under a CC BY-NC 4.0 license as a one-time purchase for approximately $11.90, permitting copying, modification and redistribution for non-commercial purposes.
