STEWARD OBSERVATORY MIRROR LAB AT THE UNIVERSITY OF ARIZONA

This facility had its beginning in the backyard of
its founder, Dr. Roger Angel. After much experimenting, and funding from the Air Force, U of A and the National Science Foundation, the facility was set up under the stadium at the U of A. It is the only place in the world where these giant mirrors for telescopes are made.
Darrell & I have had this on our list of things to do since we moved here....sometimes these things take a while to get around to!
