IC 405, the Flaming Star Nebula, appears in this 20-hour dataset captured between October and December 2025. The collection combines broadband imaging with narrowband hydrogen-alpha data, totaling 240 frames across five filters. Luminance exposures contribute 34 frames at 300 seconds each, while color channels include 32 green, 54 blue, and 20 red frames at matching exposure lengths. The hydrogen-alpha component adds substantial depth with 100 frames of 300-second exposures through an Antlia 3-nanometer filter. Imaging was performed using a Sky-Watcher Esprit 120mm telescope paired with a ZWO ASI2600MM Pro monochrome camera on an AM5 mount. All filters are Antlia 2-inch models. The dataset is available under CC0 1.0 Universal license for approximately $19.90 as a one-time purchase, providing calibrated sub-exposures suitable for custom processing of this emission nebula in Auriga.
