This dataset captures NGC 2237, commonly known as the Rosette Nebula, through 12 hours of total integration time collected between February 5 and 8, 2026. The acquisition employed an Askar 71F telescope paired with a ZWO ASI 533MC Pro camera on an AM3 mount. The imaging strategy combined two narrowband filters: 120 frames through an Optolong L-Extreme HA-OIII 7nm filter at 180 seconds each, and another 120 frames using an Askar Color Magic D2 SII-OIII 6nm filter with identical exposure times. This dual-filter approach provides comprehensive coverage of the nebula's emission lines, offering flexibility for processing in various color palettes. The data is available as a one-time purchase for approximately $7.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
