You know, I've seen this opinion expressed many times. It's a very common opinion within photographic circles. I've even fallen under its spell, though I have no experience with "mirror" lenses. But in astronomy, even at the low end of the price and capability spectrum, folks seem to prefer "mirror" telescopes. Is there some sort of paradox here, or does it all have to do with the prohibitive expense of a refractive telescope/lens with 6" or larger elements? TTYL, DougF KG4LMZ
