I can only take my hat off for the 3 images, they are very good, indeed. How much time do you spend on focusing etc?

I have just dug my microscope out again, and of course I cannot find the sw for it, so I can't even try it again.... the drive loads automatically, but I need a bit more, right?

Here is a shot I made with one of the USB microscopes. I modified the instrument, I added a filter to soften the LED lighting. And I added a yellow filter to remove the LED blue color. And I removed the front clear piece, so that I could get closer to the coin's surface. It takes some time to focus, but I am getting better at it. The text was inserted with Photoshop.
The image is now kind of poor as I had to lower the resolution to post here. The original image is much better and sharper. High resolutions and high magnifications are needed for some studies. So there are times when 30x is NOT enough. This image is about 50x.

[Concerning the above image of the "D" mint mark]....I have seen some slightly better images done with better microscopes, the binocular type, with attached cameras. But for the low cost, the USB microscopes can work, they produce an acceptable image. They require a bit more work to get just the right shot, but they work!
