The first one shows a side by side comparison at 5x. The scanner lens looks just a tad sharper, but it could also be due to the difference in lighting.
The second one shows the result when taken with the scope at 18x.
My next tests will be with the scanner lens at higher magnifications, to see if the resolution at 5x is limited by the lens or the CCD.
