No free cut lunches today folks. Ouch, so much for the marketing hype. Not one but two of these tested badly. Strehl ratio of .56! I think if I rubbed my bathroom mirror hard enough with 180 grit and windex, I might get a better ratio! Very scary. Thanks for this info Mark. The proof is in the optical stats not the pretty pictures as you can partly improvise in processing, but only to a limit.
