Piggy-backing a camera on a monocular microscope

I have had a lot of fun with this :-)
There is a cheap (~£7) but strong clamp that will fit onto most medium-sized monoular tubes (up to about 42mm diameter) onto this one can attach an Arca style camera tripod plate once the clamp's 3/8 inch reducing bush is removed.

A thick washer needs placing between the two to allow the jaws to open fully [and if that isnt enough to allow it to open around the tube, a small amount can be filed off the edge of the mounting plate].

To get as little wobble/droop as possible it seems that the rubber pads inside the jaws need to be removed.

Then one can use the microscope as a combined tripod and focusing rail:-)

I have used this with the microscope set vertical and the camera looking straight down at a petri dish ... if the stage has simple clips then a sheet of plastic or similar can be pushed underneath them to make make an extension to the stage to rest things on.
The current iteration is a bit of 2mm roofing lead bolted to the stage this has a a chinese overstage on the end of it to give a bit of x-y adjustment.
To get a bit of Z adjustment I am trying yet another bit of lead attached to the front of the overstage (to make this easy to bend this has been cut into with a pair of scissors.)

Using lead sheet nearly means that no forethought/design is required ;-)

Maybe it is now a bit over-developed.
It started life like this:

which was handy enough.



Here is a pic of how the back of the Utebit quick-release plate was filed away to let the tube-clamp jaws fully open:

I have had many fights in the past with the inbuilt tripod quick release plates and so using the Arca style quick-release was a revelation:-)
