“When Italian astronomer Galileo Galilei heard rumors of the first practical telescope at the beginning of the 17th century, he was quick to craft his own version and turn it toward the heavens.” This was the time that Hans Lippershey invented telescopes, so he could look more closely at the stars. Hans Lippershey was the first person to invent a telescope, in 1608. After that, telescopes have been becoming more advanced than that.

Like copper rods, mirrors, lenses, etc. It must cost a fortune to make it,
