If those are 5 mil traces with 5 mil spacing, then you might get better performance with a simple smartphone camera. The built in superresoloution algorithms seem to do a decent job on PCB's.
Yes, I've got the camera bodies, the macro lens, some historical experience stitching the pictures together to form panoramas, and I've just gotten into microscopy and am pretty sure I've got the microscope base he's using too. So I can see an alternative universe where I wrote this xD.
One of the first things I thought when I started was "how can I get the big camera onto the microscope" and the embarrassing conclusion I came to, is if you've got an expensive phone you can get cheap plastic adaptors and just attach it to the microscope body. Basic stereo microscopes are incredibly cheap these days, as are the phone attachments. I use droidcam obs to stream video so I don't even have to physically look into the microscopes any more. The main thing is going into the phone and getting some practice getting everything on manual so phone photo software doesn't do funky things.
My use case is slightly different, but the underlying principles are the same and I'm pretty sure the microscope hardware is identical to that in the post, so rather than rigging up a custom attachment to the expensive camera, I just rig up the phone camera to the already existent hardware of the microscope.
