Hi, earlier this year I bought an extremely very excellent (as one of my former colleagues would say) little device called an Emoscop to supplement my 4x and 8x lupes for looking at slides. You can read all about it here: http://www.greenspun.com/bboard/q-and-a-fetch-msg.tcl?msg_id=002zAl
It's a little device that originated in the Leitz workshops in the 1920s or 30s and is now made in China. It "is a telescope, a microscope and three loups all in a 2" tube". --- Bob > I agree, this is the only way to really see differences, I too bought a 20/40x > binocular microscope (old school type), using an instrument like this reveals > far more than an 8x loupe.
