Extension tubes - follow up

Ok, following on from Mike's query a few weeks ago re extension tubes, I am going to get Steve from mogg adapters to see if he can tool it up.

I would estimate that at the moment, my toucam ccd is say 50mm away from the top lens surface, so i have another 50mm to go to get the televue stated 100mm for the 7.7x.

When they say top surface, i assume they mean the lens surface, not the top of the actual powermate.

Anyone have any more accurate measurements???
