The camera port is connected to the optical path via a movable half-silver mirror.  A level at back of body moves the mirror in or out of way.  For this particular scope, the stereo function is preserved when camera port is in use, but the view is dimmer.  Other models will loss one eye when the camera port is in use.

My other stereo microscope is the Bausch Lomb brand like the one in eBay.  It is the workhorse inspection microscope 20-30 years ago.  The optics is decent and there are many attachments available for it.  You will need a ring light (preferred) or a light stick as shown in my picture.  You'll also need a boom stand.  The eyepieces are removable, so you can easily remove one and insert a camera.  You should be able to buy the basic microscope body for $100.

Dont use that kind of camera, use a normal digital camera with a telescopic lens that matches the diameter of the stereo microscope eye piece.

Those camras have poof optics, and low resolution.

Edit to add: Why would you buy a new camera when you could use an adapter to use a known good camera?
Or have one made?

I too am learning... the older I get the more I have to learn and the greater the feeling that I won't have enough time.
Thank you both for this discussion.

Very true. It took me one week to familiar with new min iPad. I will never try to set up such a system to take picture of coin.

Cool.  You KNOW we are waiting for the cool "insects in amber" thread, too.

Numismatist, entomologist, same stuff.

An awesome trick N31 N31,

Discovered the same thing in Costa Rica photographing birds in the jungle.  I had brought an expensive Canon digital SLR Camera with a tripod and a high end 300x zoom lens.   My son got much better pictures from his $100 pocket camera by placing the lens right up against the guides spotting scope on the same tripod!

This is a very famous counterfeit version appears in Chinese coin market about 5 years ago. I remember when it first comes to the market, it puzzles many people but now it is a common know counterfeit type. I circle around several transfer die damage(同模伤) and you will find more maybe.
