A double-bass player and engineer I used to work with both here at QSC and earlier at Crest Audio (in fact, he got me in touch with the people at QSC who hired me), Mike Lemp, is quite an amateur astronomer. So much so that he left a few years ago to start his own company (
www.yamcon.com) to develop an idea he came up with: a device that would identify the star, planet, or other celestial body that you view through it, without any need to first orient it to a reference star. The device uses GPS to determine the viewer's position and the time, magnetic sensors to determine the compass direction it's pointing, and an accelerometer to determine what angle it's being held at. It uses this information along with a large built-in database to determine what the viewer is looking at.
After several years of development, working out bugs, seeking investment capital, etc., he's seeing his product finally being manufactured and sold by Celestron. I hope it does well for him!
