Dear Pat,
we are facing the same problem and the most effective solution I found
is to print support for smartphones, which today offer incredibly good
cameras. Here are two examples of open access designs:

Next step is to build a low cost crystallization plate imager...
Cheers,
Claude

Hi Pat
Depends on how much you want to spend.
I’d start with a web search for “webcam astrophotography”, which should show
options on how to remove a webcam’s lens and mount the cam (not the kens, of
course!) on another optical instrument.
Back in the day, I had a Philips webcam that had a screw-out lens - this device
was used by amateur astronomers as a cheap way into astrophorography. Philips
no longer seem to make webcams, but (from what I remember) this was
plug-and-play, and used the drivers on my Mac.
You could go for a mirrorless interchangeable lens camera - Nikon actually have
their own webcam utility to turn your DSLR/mirrorless into a suitable device,
and this would be most likely to use the SLR mount. E-Bay have Nikon bodies
starting at around $200 today.

Greetings, hive mind,
We have an old (but still useful) Nikon SMZ stereomicroscope that we use for
mounting crystals. I’d like to attach a digital camera to the phototube, both
to capture crystal images for archival purposes, and also to live-stream as a
teaching tool.
I’d be grateful for any suggestions for an inexpensive option here.
When this camera was new we used it with an SLR that captured images on *film*
(this is where the students gasp). We’ve since gone through one digital camera
that probably still works, but the interface and software have become
obsolescent. Meanwhile, the microscope keeps on truckin’; interesting to
reflect on the relative lifetimes of analog vs. digital tools…
Thanks in advance for any suggestions,
Pat
