WebGalileo’s Refracting Telescope. In May 1609, Galileo had heard about a tool using lenses that could make far things appear close. He immediately made one of his own out of a tube and two lenses. His telescope was a big hit in Padua and Venice, and the Paduan Senate gave him 1000 florins per year and a professorship for the invention, which ...

WebJul 3, 2024 · From the historical record, it appears that Lippershey was the first to use a pair of lenses in this way. However, he may not have been the first to actually experiment with combining lenses to create crude telescopes and binoculars.

My budget is ~350-ish for the scope and ~350-ish for the stand/tripod. I can probably squeeze a bit more for other components, but that's the ballpark range.
