@normb Yep. Removing the clear protector on the front will enable you to turn the black pointy part, which I assume has a lens in it. This will change the magnification. Try it in various positions.
Aside from that, everything has to be perfectly still. You need a microscope stand that is rigid, and if your table has suspension, you have to defeat it. Minimizing vibrations are very important. Just my HVAC running would cause a blurry image. When you’re ready to snap a photo, press the button in the app, not on the cable, to minimize movement.
Lighting is also extremely important, but it’s difficult to get right with the microscope so close to the stylus. Try other sources of lighting in addition to or instead of the built in LEDs.
It is not easy.
