Thanks for dating my AS. That is very interesting about export vs non-export. I guess it was the Telementor I and II that were never exported? Earlier Zeiss telescopes were allowed to be exported? And, I guess it was the infamous law suit between Zeiss Jena and Zeiss Oberkochen (sp?) that dictated how exported Zeiss telescopes could be labelled?
I would love to hear a concise history of that period of Zeiss. It was never really clear to me.
And, thanks for the comparison between the Telementor I helical and AS helical.
Is there any way to determine roughly the age of the lens cell without the serial number? I wonder if my lens cell is original or not.
Finally, does any one have a Zeiss catalog that has this version of the AS in it? I have about 15 different Zeiss telescope catalogs, but none that have the later version of the AS63.
Oh -- last night was first light. At 84x, no discernible spurious color on the moon or Jupiter. None at all. No image break down either -- obvious that this little Zeiss can handle higher powers. But, an O-10 is as high as I have at the moment. Anyway, images were very sharp. Didn't do a star test -- I'll have to do that later. And, a critical side-by-side with my Telementors. Although, from memory, I'd say that the AS is a bit higher contrast and less color.
