Thanks for everyones help.
I made an attempt using a 5x and also a 2.5x powermate on a Canon 1000d and then used "EOS Movie record" to capture video/stills.
This I feel is where I ran into troubles by asking for too much magnification from the PST.
A quality image could not be achieved, the result from stacking was terrible to say the least.
I've been considering getting a OSC, but this maybe some time off yet
below is a link displaying what video i did capture using the method described.
Thanks again for everyones help
