I am in need of help from the gurus. I am considering purchasing a coated Apochromatic Artar, not a Red Dot, by American Optical Co., serial #777xxx. The article on the forum home page claims that there was a design change when American Optical went from the Apochromatic Artar to the Red Dot Artar lens. Is this in fact the case? Do these lenses differ significantly, if so does anyone know in what sort of fashion, and does the Red Dot produce a superior image (in the hands of a competent image maker, of course)? Any information, advice, and admonitions are most appreciated.
Thanks,
Larry
