Interesting coincidence, this week my daughter is visiting from the Bay area of California, where she works as a hair stylist. Just a few days before coming here, a walk-in client turned out to be the production manager of either the James Webb or Magellan scope at Lockheed (she wasn't sure), but was excited when he told her. "My dad would love to talk to you!". Haha. /R From: Robert Taylor <ratskradmt@gmail.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Thursday, August 27, 2015 11:00 AM Subject: Re: [Utah-astronomy] Making a 36" from many smaller mirrors
The U of A mirror lab has for the last 8 years been making the mirrors for the Giant Magellan Telescope which is comprised of seven 8.4 meter mirrors. The center mirror is a normal shaped mirror and the 6 outside mirrors are ground off center so when put together creates a mirror that is 25+ meters across. In 2009 when I spent time in Tucson I used to go to the mirror lab with Dean Ketelsen who was one of the lead opticians there. He retired a few years ago but as things are he still works there because there are very few in the world who can do what he does. When done the GMT will have adaptive optics and so the mirrors will be adjusted often depending on conditions of the sky.
