Hi John,

Thanks for info. Well, its nice to see that they exist...at least in a form
that is not "observatory priced".   

If I come up with nothing, I'll send Al a letter asking him the story.  Man,
would I love to have one of those 4" 100mm pieces though!  Must weigh more
than a 20mm Type II if that's possible.

I did get a catogue coming from Edmond...the guy claimed to have 3" and 4"
lens of the kind Bratislav suggested would work. I'll let ya know how they
work out later.
