Subject: RE: [Utah-astronomy] Lasers and collimation questions The book is not currently available at Barns & Nobel. There are 2 book available from Amazon.com (sort of).

I leafed-through it years ago, will pick up a copy and read it in detail. My editor at S&T recommeded it too, for some reason I didn't buy it at the time. For those interested in the star-test, both for mirror evaluation & collimation, I suggest Dick Suiter's book "Star-Testing Astronomical Telescopes". Might be a bit "long-haired" for the casual observer, but contains a wealth of information. C. --- "Don J.
