Astrolabe
An astrolabe is a portable astronomical calculator that could show how the sky would look when standing at a particular place at a particular time. With one, a person could determine the time of day or night, figure out when the sun would rise and set and find the positions of certain stars. This brass astrolabe dates to about A.D. 832 and corresponds to latitudes between the Black Sea and Persia.

it is very informative, i knew about only the telescope and the compass. One doubt, did Galileo made all the instruments or he used others work for his discoveries? Please clear this doubt.

Amateurs interested in astronomy are often told to star with a decent pair of binoculars which are usually about 7 to 10 powers of magnification. It's easy to see how Galileo was able to make his discoveries with a telescope of about the same power.
