It was a very interesting trip and the technology being used was fascinating. To prove out the process, they started by grinding a concrete blank. It was the smoothest piece of concrete you had every seen! <br /><br />The mirrors are also ridiculously thin and would break if it wasn't for the adaptive supports behind them. Really great trip and a total surprise since I was really visiting a sister company.<br /><br />73 Paul M1CNKPaul Whttps://www.blogger.com/profile/12301496237556686902noreply@blogger.comtag:blogger.com,1999:blog-7590176649168185428.post-32612978150618645092011-05-31T16:25:45.140-04:002011-05-31T16:25:45.140-04:00The laser is projecting a "virtual star"...The laser is projecting a "virtual star" in our atmosphere, allowing the telescope to computationally subtract the "twinkle" caused by turbulent air from the other stars in the image.Bryanhttps://www.blogger.com/profile/15253037109152402500noreply@blogger.comtag:blogger.com,1999:blog-7590176649168185428.post-29732011544976760902011-05-31T12:08:50.781-04:002011-05-31T12:08:50.781-04:00Anybody know what the laser was doing?
