I go to the Southern California Linux Exposition every year, and there's always a couple of booths set up with telescope stuff.
There's a great open source program called Stellarium that basically simulates a planetarium on your PC. Also has builds for Windows and Android that I know of. It is able to point telescopes as well, although not to track, just to aim and let the internal sidereal motor control take over.
Are these weatherproof at all?
Not at all. I doubt you'll find one that is, since stargazing isn't much fun when it's cloudy, let alone raining! But I want it for portable use, like during field day (and because it's an interesting hack). I was thinking that a tent might be able to act like a radome if the weather gets bad.
