Nope, you got it right. No camera is shown because I used it to take the pics of the setup
In fact, this capability was a prime reason for putting this sort of setup together, so I could use my camera for coin photography, remove it from the setup for family, ebay, whatever photos, then go right back to taking coin pics AS IF I WAS CHANGING A LENS.
That's the key, ie the setup appears to the camera as if it's a manual lens. The bellows allows magnification adjustment, while the actual lens mounted on the bellows has the aperture adjustment. The microscope stand moves it all up and down to adjust focus.
It is important that whatever DSLR you choose for such a setup be able to work with manual lenses. I think most DSLR's will "work" with manual lenses, though some offer more functionality than others. Ultimately, if the DSLR can be "tethered" to your PC to control its functions, provide a preview of the image for focusing, etc this is the recommended way of using a setup like this.
Hope this explanation helps with understanding the setup...Ray
