astrometry.net

Astrometry.net is an online tool that helps astronomers identify and analyze images of celestial objects. By uploading a photograph of a star field, users can automatically match the stars in the image to a vast database of known star positions. This process is called astrometry, which involves measuring the positions and movements of celestial bodies. Astrometry.net makes it easier for both amateur and professional astronomers to understand their observations, pinpoint specific stars or constellations, and contribute to astronomical research by providing precise location data.
