Are you referring to another thread where I said: "I just got Orion's catalog #046 with the 100mm ED on the cover. And while I wouldn't exactly call these high end refractors, they certainly MAY offer the best value for the money out there (though just how good the 100 is remains to be seen)... If you are referring to this, please note that I put TWO qualifiers in there... One, that I wouldn't call these high end refractors, and two, it remains to be seen just how good they are... And I also capitalized the word MAY, so as to emphasize that "best value for the money" hasn't been proven yet... I think a company can deliver good value without including 4" state of the art focusers, and CNC machined tubes, for those who are looking for a fine view without frills... Right now, Orion is looking more and more like a potential candidate for honors in this category. Your mileage may vary...
