This dataset captures the Heart Nebula (IC 1805) and its companion, the Soul Nebula (IC 1848), over 13.33 hours of total integration time. The data were acquired between October 11 and October 14, 2025, using a Nikon 240mm f/5.6 lens paired with a ZWO ASI2600MC Air camera on an AM5N mount. The imaging session comprised 90 frames through an Askar E1 Dual Band 3nm Hα+OIII filter at 300 seconds each, plus 70 frames through an Askar E2 Dual Band 3nm SII+OIII filter, also at 300 seconds per exposure. This dual narrowband approach isolates emission from ionized hydrogen, oxygen, and sulfur, revealing the nebulae's intricate structure and star-forming regions in the constellation Cassiopeia. The dataset is available as a one-time purchase for approximately $14.90 under a CC BY-NC 4.0 license, permitting copying, modification, and redistribution for non-commercial purposes.
