Heart of the Heart comprises 9.47 hours of narrowband and RGB integration captured over two nights in early January 2026. The dataset includes 30 hydrogen-alpha frames at 300 seconds each, 37 oxygen-III frames at 300 seconds, and 34 sulfur-II frames at 300 seconds, providing a robust foundation for Hubble palette or other false-color processing. Supporting RGB data consists of 23 red, 20 green, and 20 blue frames at 60 seconds per exposure, all acquired through Touptek filters with an ATR585M camera. The imaging train used an Askar 103 APO refractor on a Star-Adventurer Wave 100i mount.
