The results are good!
I have in the past tried the EOS with the usual projection-eyepiece (a x2.5 Meiji which wasn't cheap!) and suitable adapter to hold the camera and eyepiece mounted onto my 'scope's trinocular tube - with very disappointing results - leading me to put away the DSLR and revert to the super but limited Toupcam 2mp...
This time I bought a 'universal adapter' (from Brunel Microscopes, who else?) with built-in x2 reduction optics to sit between the DSLR and the trinocular tube - the Meiji projection eyepiece is languishing in a drawer where it can't give me any more trouble and disappointment!
I controlled the DSLR remotely (tethered) from a Windows 7 laptop using canon's super EOS utility that is package free with the camera - very nice it is too, with good results.
However the full-blown laptop seemed a bit big and got in the way on my desk set up this way so I looked around for an alternative - and found software (purchased from Google's Play store) that is able to not only do the same job of controlling the 1200D via a tether (USB cable that is) as the Canon software, but to do this with many more control-functions for the camera and from my Android (v4.4) 10" tablet - all touchscreen controlled!
To cut a long story short here are some pictures of the setup I now use and a link to a 6-7 minute video (rather poorly shot by myself - sorry...) of the software running and being used to control my Canon and of course to take pictures through my 'scope...
The rig, The adapter & mounted DSLR (Canon 1200D), Camera may be used as a standalone (i.e. untethered) via it's 'live-view' capability.. The control-software running on my Andoid v4.4 tablet showing image through 'scope as 'seen' by the camera.. Here's my rather poorly-shot video of the software and tablet controlling the DSLR for photomicrography! Touch-screen control of the Canon EOS 1200D mounted on a microscope with 18mp to play with!

This setup runs & performs perfectly and extra-fine-focus is easily achieved as the 'scope and camera are par-focal - after I added a 'spacer' to raise the camera about 6mm above it's default position atop the trinocular tube. I simply put a metal clip onto the end of the tube to add a little height to the camera's position - worked perfectly. The software has the ability to magnify the image live and this is superb for the very fine focus needed for stacking etc as well as sharp single photomicrographs.
The Android EOS Control app costs about £5 - and works perfectly for my rig!
