One of my 3D printer projects was to make an adapter to allow a web cam to mount on a microscope. That let's me shoot video and still images of anything I can see with the microscope. The camera is a Logitech Quickcam Pro For Notebooks (why don't they just use model numbers?), and video was captured using gUVCview.
I actually made two different
adapters to fit the same camera on two different microscopes I have in
my collection. One is a binocular surgical microscope and the
other is a biological microscope. You can see some test video I
shot with the biological microscope here:
