I am reading books on how to make your own telescope. It occurs to me that I haven't seen books on how to make your own microscope. Are there any and are there groups of amateurs devoted to this activity ? Allan Adler ghot@ms.uky.edu

(yeah, yeah,...the publisher thought it looked good) aimed at amateur science enthusiasts has an article on how to make van Leeuwenhoek-type microscope. Glass, liquid, glass-liquid lens systems. Looks like fun, actually. As to making more sophisticated microscopes, you could probably develop a 19th- century-Zeiss type microscope from that start pretty easily. That would be about the same scale of difficulty as making a small refractor, but smaller. -- ------------ The only drawback with morning is that it comes at such an inconvenient time of day. ------------

I have successfully made these from commercial mirrors. These can get to numerical apertures of roughly 0.5. Doug McDonald * * * * * * * * * Object * * *Image * * * * * * * * *

I don't mean to be a grinch, and this is admittedly an alt. group, but telescope and microscope design is not appropriate here.... -- Peter Whittaker [~~~~~~~~~~~~~~~~~~~~~~~~~~] Open Systems Integration pww@bnr.ca [ ] Bell Northern Research Ph: +1 613 765 2064 [ ] P.O.

Hmmm, at least I wasn't the only one who failed to read the cross-post list before jumping in.....
