5.0 out of 5 stars Great little device, for the money, December 29, 2010
Verified Purchase(What's this?)
This review is from: Celestron 44302 Handheld Digital Microscope 1.3MP (Electronics)
As other reviewers mentioned, I had no trouble getting this to work under Linux. I'm using Ubuntu 10.04. All I did was install and run guvcview and it worked right away.

Another reviewer complained about the images being over-exposed and I've seen several complaints about the lights being too bright, but I think these are really both autoexposure problems, which can easily be overcome by software and a little user education. guvcview lets you override the exposure setting, as well as enable/disable backlight compensation. I initially had washed out images of a white object on a black background, but overriding the exposure allowed me to see the all of the details. Avoid the temptation to play with brightness & contrast, though, as exposure is usually what you want to adjust. Brightness & contrast can be useful for exaggerating subtle differences in shading, but shouldn't be used to compensate for underexposure or overexposure.

I don't know if the included windows software gives you these controls. If not, I'd look for a 3rd party software application to use with the device. It might provide you with a much more satisfying usage experience.

Yes, the single control for focus & zoom is not ideal, nor is it easy to actuate without moving the scope. Both are understandable and acceptable compromises, given the price. I'd much rather they did this, than cut costs on the sensor, lights, or other aspects. I'm glad there's a cheap and simple device of this quality and I'm happy I bought it.
