IC 405, commonly known as the Flaming Star Nebula, is captured in this 10-hour narrowband dataset. The acquisition spans November 21 to 22, 2025, using an Askar 65PHQ Quintuple APO telescope paired with a ZWO ASI294Mc Pro camera on an HEQ5 pro mount. The data consists of 120 frames at 300 seconds each through a Svbony sv220 Ha OIII dual narrowband filter, isolating hydrogen-alpha and oxygen-III emission lines that reveal the nebula's complex ionization structure. This emission nebula in Auriga surrounds the variable star AE Aurigae, whose intense ultraviolet radiation illuminates surrounding gas and dust. The dataset is available as a free download under CC BY 4.0 license, permitting copy, modification and redistribution with appropriate attribution to the author.
