The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.
the 17th century
The first telescopes actually came from China. Galileo of Italy perfected a telescope in the 1600's.
Telescopes were invented in the Netherlands in the 17th century.
We know the telescope was invented by 1608 and soon many people, for example Galileo, were using telescopes. There is some evidence of earlier telescopes, but we aren't certain about that. So, humans have been using telescopes for about 400 years.
They have changed because now there is a telescope in space called the "Hubble". I can see things that regular telescopes on Earth cannot see.
The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
it back to the time of newton about 400 years back, newton first invented reflecting telescopes!
