The Heart Nebula (IC 1805), located about 7,500 light-years away in the constellation Cassiopeia, is a vast region of glowing hydrogen gas and dark dust shaped by powerful stellar winds from the young star cluster Melotte 15 at its core. This image, captured remotely from Starfront Observatory in 30 September 2025, showcases the deep red heart of the nebula formed by ionized hydrogen and faint oxygen filaments weaving through it. Captured with a William Optics RedCat 91 WIFD telescope, ZWO AM5N mount, ZWO ASI2600MM-Pro camera, WO UniGuide 32 with ASI120MM-Mini for guiding, ZWO EAF, CAA, EFW Pro, and Pegasus Astro UPB. Total integration time: 31 minutes 40 seconds, consisting of Ha: 88 × 300s (7 minutes 20 seconds), OIII: 188 × 300s (15 minutes 40 seconds), SII: 80 × 300s (6 minutes 40 seconds), and RGB: 20 × 120s each (~40 seconds per channel).
