Hi Les, My records show that you ordered a 2" thick specifically 54" custom focal length mirror and received one, after a number of months lead-time. I do not have a different standard of mirror for myself vs anyone else, and never have had. Please PM if you want to debate that further.
If your purpose was to spell out to the public, that 'by comparison' with your own premium mirror, that you thought your mass-produced optic review telescope was optically really , really , really ,really good, then you probably succeeded.
As to the rest of your optical review and comparison with a review telescope its hard to comment other than the obvious missing comparative technical details of the 'experiment' , like coatings and relative thermo-mechanical conditions , my colleagues and I are asking the same question: What exactly is your point on the basis of a sample of one , with specific reference to the average person who will buy such a mass -produced telescope on the street ?
Regards
Satchmo
