This dataset captures the Leo Triplet, a striking group of interacting galaxies in the constellation Leo, with nearly 13.6 hours of total integration time. The data was acquired over two nights in late February 2025 using a Sky-Watcher Esprit 120mm refractor and ZWO ASI2600MM Pro monochrome camera on an AM3 mount. The collection comprises 333 luminance frames at 120 seconds each through an Antlia 2-inch filter, supplemented by 25 frames in each of red, green, and blue channels using matching Antlia filters. This LRGB dataset provides detailed structural information across the three galaxies: M65, M66, and the edge-on NGC 3628. The raw frames are available as a free download under a CC BY 4.0 license, allowing users to copy, modify, and redistribute the material with appropriate attribution to the original author.
