Telescope Timeline – Timeline Help

A telescope is a device to view, discover and study objects that are far away. There are many very large telescopes in the world to study planets and our universe. And bigger ones are being built, at this very moment. I will take you back to the beginning of our era. To the first signs, inventions, and developments that later resulted in modern telescopes.
All glass inventions, refractor devices and of course the honorable inventors are in this Telescope Timeline.
