Shock !
No wonder i couldnt see how this worked.
All through the thread, it appeared that it was inside the focuser tube, not the extension tubes.
Just read the whole thread again, and in 1 post, you mention its in your ext. tubes, and must of missed it

The extension tube shown in the photo is the one I put into the scope so in essence, the bit with the diaphragm blades is well up inside the focuser. I can also unscrew the black part from the chrome barrel and seeing as it's also 2" it will happily sit up inside the focuser without needing to be joined to the extension tube.

8-PYou can still do it. Place a short tube up the focuser shaft so that it would stay there as a stop. Then you can insert disc of various size to sit on the stopper.
