This dataset captures IC 1805, the Heart Nebula, through 25.17 hours of narrowband integration acquired between September 2024 and August 2025. The collection comprises 302 frames distributed across three Antlia 3nm filters: 79 H-alpha exposures at 300 seconds each, 111 OIII frames, and 112 SII frames, all at matching five-minute exposures. Imaging was performed with an Askar PHQ107 telescope paired with a QHY268M monochrome camera on a ZWO AM5 mount.
The tri-band narrowband approach isolates emission from ionized hydrogen, doubly ionized oxygen, and singly ionized sulfur, enabling detailed mapping of this emission nebula's structure in the Perseus arm. The dataset is offered under a CC0 1.0 Universal license with no copyright restrictions, available as a one-time purchase at approximately $20.90.
