A tip of the hat to our own Bill Kelley, who was again cited in S&T in the current Telescope Techniques column. Author Pfannenschmidt describes how he used Bill's original method to flex a cheap spherical mirror into a much higher-quality paraboloid. It's basically just a rewrite of Bill's original article some ten years ago, but a good read in it's own right. C. __________________________________ Do you Yahoo!? Yahoo!
