A copper astrolabe consisting of a round shaft ends on the top with a pointed tip bordered by a lobed frame. There is a metal ring at the top, by means of which the astrolabe can be hung up.

The shaft is divided into equal portions, while the frame bears numbers related to astronomy and the stars. At the upper part of the astrolabe shaft there is an additional geometrical formation, made of brass. In the middle there is a circle with a metal indicator. Drawings are carved on parts of it that represent astrological signs and constellations. The astrolabe shaft has various geometrical parts.

Muslims used the astrolabe to find the direction of prayer (the direction of Mecca) and its declination. It was also used for the declination of countries, and to estimate the height of the sun, the celestial bodies and their declination and distance. They also used it to measure the day and the night and the number of hours in each.
