Dear Dave,

thank you for sharing your experience. The review of macroscope
configurations is being built here:
http://confocal-manawatu.pbworks.com/w/page/16346953/Macroscopes

I have a feeling however that Mark is after something closer to the
optical configuration close to the stereo microscopes:

That is a matter of the lenses used, of course.

Many thanks again,
Dmitry
