From the “professional” side:For a long time, I would have sworn my Nikon Prostar had better edge performance than the FMT … until I set up a “professional” resolution test. The Prostar resolved the resolution chart (1951 Air Force) all the way out of sight; the FMT-SX resolved the chart all the way out of sight.From the “non-professional” side:My first telescope was a 3-inch Gilbert in a paper tube with a two element eyepiece. With it, I saw Jupiter, Saturn, Mars, Venus, M-42, and m-31. That was 1965.Since then, I’ve owned several pretty fine telescopes. With them, I have seen coma, astigmatism, chromatic aberration, field curvature, etc.When do you think I was most happy? :cat:Bill</blockquote>
