IC 4592, the Blue Horsehead Nebula, is a reflection nebula captured across 21.2 hours of total integration time between April 10 and May 9, 2026. The dataset comprises 254 frames acquired with a Sky-Watcher Esprit 120mm refractor and ZWO ASI2600MM Pro camera on an AM5 mount. Luminance data dominates with 163 frames at 300 seconds each through an Antlia 2-inch filter, while color channels include 25 red, 41 blue, and 25 green frames, all at matching 300-second exposures.
This CC0 licensed dataset is available for one-time purchase at approximately $22.90, offering unrestricted use for processing, research, or publication. The multi-filter approach provides flexibility for narrowband composites or traditional LRGB workflows targeting this distinctive dust cloud in Scorpius.
