I'm still trying to figure out exactly how to do this. The microscope *I* used isn't very good and only went to 40x. I had to take pictures by holding my digital camera to the eye piece. At the university we have a metallurgy microscope with a hard mounted camera. I might try to look with that one too.

That's what I was able to get with the work microscope and a digital camera held up to the eye piece.
