Review on Celestron 44347 TetraView Digital Microscope by Anthony Mayes

I have been working as a scientist with microscopes for many years. I know that a good microscope can be very expensive, so I didn't have high expectations for it. I regret to say that this microscope was completely unusable. The focus knob doesn't lock the stage, so the plane of focus is constantly changing when you're trying to take a picture. The screen resolution is also very low, making it almost impossible to focus properly when using higher magnification (thinner focal plane) lenses.
