I was up and running again in 30 seconds – I kid you not!  This article describes how it works for those who might be interested.

Celestron Digital Microscope Imager

We recently moved to a small farm and we have been looking at our soil biology under a microscope. It was hard to see clearly so we bought a ‘Celestron’ Microscope camera (model #44421)  from Amazon for about $40.
