Here is a interesting lecture I found on archive.org on the
History of Telescopes and Binoculars
It's a University of Arizona lecture.
Bio: John Greivenkamp is a professor of optical sciences at the University of Arizona,
where he has taught courses in optical engineering since 1991. He is a fellow of SPIE
and of the Optical Society (OSA). John passed away last year. A good friend of many
us in the optics field. He invited me to lecture there a few years ago to over 120 students
I donated a few one of kind optics for the museum, free forms lens, like the Alvarez lens.
