This dataset captures the Andromeda Galaxy (NGC 224, also known as M31) over two nights in mid-July 2007. The acquisition consists of nine unfiltered frames at 480 seconds each, totaling 1.2 hours of integration time. Imaging was performed with a Sky-Watcher 80ED refractor and a Canon 350D camera, mounted on a Vixen Super Polaris.
The data is released under a CC0 1.0 Universal license, placing it in the public domain with no copyright restrictions. It is available as a free download. This modest integration time on one of the sky's most prominent spiral galaxies offers raw material suitable for educational projects, processing experiments, or integration with additional datasets.
