Did The Chinese Invent the Telescope ???

Well I read that eye glasses were invented in China. We are told that a
Dutch lens-grinder (Hans ????) can't think of his last name invented the
telescope in 1608,and the next year Galileo comes up with his. Not sure
but I think Galileo's scope had a magnification of about 30. Who
invented the reflecter telescope? Was it Newton? It must have been the
rage to own one. Still is. Bert

Thanks CeeBee Even if I thought of it I would never be able to spell his
last name. One thing is for sure CeeBee nothing has changed the first
person with a telescope turns to see the mountains on the moon. However
Saturn with its rings is breath taking. Someday soon magnifying light
with a lens will have had its 400 years. Someday a single photon from a
15 billion LY away quasar will be bounced around say in a laser,and come
out the laser hole with the intensity that will equal photons from the
sun.(why not?) Bert

Newton did invent the reflecting Telescope, however they were not that
popular as making large accurately figured and highly reflective first
surface mirrors took a long time to perfect. They used to make the
mirrors from metal (a shiny alloy of copper and tin was used). It wasn't
until after the mid nineteenth century that they perfected the art of
figuring and silvering glass substrates. See:
