The Englishman, Leonard Digges (1520-1559), from Bartham in Kent, UK, invented the Theodolite in 1551...The main component of a Theodolite is a small but powerful refracting telescope, so he was almost certainly the very first person in the world to invent the refracting telescope. However, it is known that he also invented the reflecting telescope shortly afterwards. In 1608, Hans Lippershey, a German born Dutch citizen invented a refracting telescope in Middelburg, Netherlands. Galileo's model a year later was a considerable improvement upon Lippersheys design but it came almost 60 years after Digges's invented his telescope. The Gregorian reflecting telescope was invented by Scottish mathematician and astronomer James Gregory and his design was first published in 1663. Isaac newton invented the Newtonian reflecting telescope in 1668, 117 years after Digges invented his. The design of the Cassegrain telescope was first published on April 25th 1672 and its invention is attributed to Laurent Cassegrain (1629-1693), a Catholic priest from Chartres, France. There were no real major advances in telescope designs until the Schmidt telescope was invented, by German optician Bernhard Schmidt, in 1930. The Maksutov telescope was patented in 1941 by Russian optician Dmitri Maksutov.

Why are reflecting telescope and refracting telescope considered as optical telescope?
"Optical", in this case, simply means that they work with light.
When did Galileo first use the telescope to study planets?
optical
How did first telescope come about?
Galileo built the first telescope in 350BC. He used it to survey the night sky.
Who built the first telescope?
The first known telescope was known to have been built by Isaac Newton, who is famous for developing the laws of gravity. Galileo later improved the telescope.
Who built the first reflecting telescope in 1668?
isaac newton

What kind of telescope are most of the large optical telescope?
Reflector.
What is the advantage of using a non-Optical telescope over an optical telescope?
See things that don't shine in the visible spectrum.
Who invented the optical light telescope?
me
Who made the first hubble telescope?
HST has actually been built under the control of NASA's Marshall Space Flight Center (responsible for design and optical part, subcontracted to Kodak and Perkin-Elmer Corp.) and Goddard Space Flight Center (science instruments and ground control). The overall spacecraft in which the telescope is housed was built by Lockheed.
