Building an 18' f/4.5 Newtonian on a GEM - Livestream

Dave made an 18" f/4.5 telescope using an "old school" design. It’s big, very big. It weighs about 520 pounds on an equatorial mount. It is capable of being a great visual scope as well as an amazing photographic instrument. Despite its size, it is portable and Dave can set it up in about 1 hour. His scope has some unique features that cannot be found on commercially made telescopes.

In this presentation, maybe you’ll be inspired to make your own telescope. You’ll learn a little about why you might want to make a telescope and some things to consider when making it.
