Telescopes have been our window into the cosmos since the time of Galileo. Today, many amateur astronomers still take great pride in building their own telescopes from scratch. Come learn all about these magnificent instruments: how they work, how they are built and used, and how with a few simple tools, a piece of glass, and your bare hands, you can grind optics that rival the precision of the Hubble itself! During the second half of the class, we'll be building and decorating small telescopes for you to take home.
