Build your own telescope

dobsonian telescope
So, did you hear about those Girl Scouts kicking ass with their home built telescope? [via] Here I thought they were only about overpriced cookies. The telescope  is a “Dobsonian”; a design over 50 years old and named for creator John Dobson. People have been building these long before commercial telescopes were available. Here is a link to a pdf describing how-to build one of these monsters.

  1. Dobson, the guy the telescope mount is named for, ground and polished his own mirrors from a decommisioned ship’s porthole glass! Check out the San Francisco Side Walk Astronomers site for more info.

  2. word. there are alot of videos on telescope lens making. <—-this is one similar to one i saw a long time ago but instead of metal arms for the grinder, he had built his out of wood. also you can use a kiln and sheet glass stacked on top of each with a fiber blanket ring in the diameter you want to lens and blast that shit together and let it anneal for a day or 2
