This dataset captures Eta Carinae, one of the most massive and luminous stellar systems in our galaxy, through 12.9 hours of narrowband imaging. The acquisition spans from November 2025 to February 2026, using a Redcat 51 telescope paired with a ZWO ASI1600MM Pro monochrome camera on a Sky-Watcher EQ6 Pro mount. The data comprises 58 frames through Baader 7nm Hydrogen-alpha (4.8 hours), 41 frames through Baader 8.5nm Oxygen-III (3.4 hours), and 56 frames through Baader 8.5nm Sulfur-II (4.7 hours), all at 300-second exposures. This combination of filters reveals the ionized gas structures surrounding the unstable supergiant star and its famous bipolar Homunculus Nebula. The dataset is available as a free download under CC BY-NC 4.0, permitting non-commercial copying, modification, and redistribution.
