I didn’t realize you had posted another post right after posting your microscope pic.
If the jewels are cemented in ok with shellac you shouldn’t have a problem. Looks like those pivots could use a good polishing! That microscope does a nice job.
Also…C_Kelly,…I sent the following links to another member yesterday and thought you may find them helpful too if you haven’t already seen them.
The first one is an interesting video you can watch of a USB camera in action. It’s a few years old but worth watching. The second one has a few different types of cameras.
Hope this helps,
