This dataset captures IC 1805, commonly known as the Heart Nebula, through 23 frames taken with an Optolong L-Ultimate Ha-OIII 2" filter. Each exposure lasted 600 seconds, accumulating 3.83 hours of total integration time. The data was acquired between November 30 and December 1, 2024, using an Askar FMA 180 Pro telescope paired with a ZWO 533MC Pro camera on an AM5 mount.
The L-Ultimate filter combines hydrogen-alpha and oxygen-III wavelengths in a single pass, allowing the camera to record both emission lines simultaneously while rejecting light pollution. This emission nebula in Cassiopeia lies approximately 7,500 light-years from Earth. The dataset is available as a one-time purchase for roughly $7.90 under a CC BY 4.0 license, permitting users to copy, modify and redistribute the material for any purpose with appropriate credit to the author.
