Highest apo price EVER!

Pardon me for interrupting/hijacking this thread, but maybe someone
can answer my question below:

I recall a refractor primary on display in the Smithsonian circa
1971, which was, if I recall the short story on the plaque associated
with it correctly, the largest refractor lens ever made, and for some
reason I forget (perhaps those involved ran out of money), no
telescope was ever built using it. It had a mirror behind it so you
could see yourself magnified through it. I recall it being "several
feet" in diameter (what's the largest refractor?). I was about 13
years old at the visit, and so may not remember correctly, but can
anyone tell me more about what I might have seen?

They built a 1.1 meter objective in France about 1900 that never
worked well enough to be useful. This was the largest refractor I
ever knew about. I don't know where the lens is now.

Go to http://astro.uchicago.edu/vtour/inside/telescopes.html and Yerkes
observatory claims to have the largest refractor in the world, a 40 incher.
They still use it.

Okay Folks,

I think you shall see at least some infos about the object of
discussion, therefore here some links

now tell me, is that not worth $ 10,000 for a collector ? :-)

When was this produced? It's got what looks like a feather touch
focuser so it's not even an original Zeiss tube and focuser.
Seems to me that if originality counts for much in terms of collectors
items (and in every other hobby it does) then wouldn't a pristine
100mm APQ with original tube, lens and focuser be worth at least as
much?

to be honest, I dont know. But from engraving and cell design, it must
be in the last days of zeiss, since if Zeiss would have continued, it
would have gone into production.

no of course not. I have had the chance to buy on ebay with the lens all
parts to have build a original tube, but it would come out even more
expensive and I self don't like to much the Zeiss styled mechanics, so
we made our own tube

yes and no. I have had already offers for the 80 mm with my tube, higher
then like new APQ 100/640 with original tubes.
What setting the price very high here, is the unique APQ 80 and its
serial Nr. 1.
The Nr 2 ( only 2 have been made) have never shown up in the market yet,
so this is the only 1 known in the market, where you can find some
100/640 somewhere

That is rare.
Something turned up at Stellafane one year (1990?).
It was a Zeiss 70mm achromat, around f7. The guy sold
it to a friend for about $100. I looked though it, definition
was of course excellent. I don't remember Zeiss ever having offered
a 70mm scope in any ads. The only small scopes I remember were the
63mm teaching refactors.
