You might be able to get a proper microscope adapter for the SLR. I found
the one for my Exakta in a camera shop for \pounds 9.00, still in
original box (no, I don't care about that, I bought it to use [1]). OK,
that's a fair amount of money for a tube, but it is a nice tube, with the
bayonet mount, a couple of extension tubes you can fit or not as you
chose, the collet to clamp to the microscope, etc. Making it up would
have taken a lot of time.

You want to find an old-fashioned sort of camera shop, preferably one
that also sells second-hand cameras. They have the most amazing bits
hidden away.

[1] I picked up a reasonable Zenith microscope with several objectives
and eypieces for 20 quid or so in a charity shop (of all places).
