Mell What were the first types of telescopes?

What was used before telescopes?
The astrolabe was originally invented by the Greeks, but made far more precise by Arab astronomers. The viewer looked through a pair of sighting holes on each end of the long arm. The face of the astrolabe held a disc that could be removed and replaced by other discs, much like a computer.

Was Galileo the first person to build a telescope?
Interestingly, Galileo wasn’t actually the first person to create this device that would later be known as the telescope, even if he was the first to use it for stargazing. It was Hans Lippershey of Holland, an eyeglass maker, who requested for a patent on a “certain instrument for seeing far” in 1608.
Who invented the modern telescope?
Isaac Newton built the first practical reflecting telescope in 1669. Modern telescopes that allow for views of our solar system and beyond are largely based on scientific principles discovered in the Middle Ages and perfected in the 1600s.
When was the first telescope first used to observe space?
Suggested by Lyman Spitzer in 1946, the first operational space telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971.
Who was the first person to see the Moon with a telescope?
