Actually I didn't have my tripod with me ... the camera still had the QR Plate in the bottom ... and I used a few mousepads for cushioning/support ... and a couple of post-it notepads to get the lens height right.
I had to improvise ... and of course the 2 sec MLU was needed ... I had a few where there was movement ... I jsut had to reshoot it and make sure there was no movement.
I did a quick read-up on magnification and how to work it out ... and due to it being closer than 1:1 ... trying to get as much in focus was hard ... especially with available light.
Actually ... here's a crappy iphone pic of my 200mm tubes setup ... as you see the desk is white and works in my favour really.
