Arabian astronomers used the astrolabe for centuries to make accurate charts of stars positions. In the 14th century, astronomer Levi ben Gurson invented the cross-staff to measure the angle between the Moon and any given star.

With each of these technological innovations, astronomers made new discoveries and gained more knowledge about what they're seeing.
