if you have one of those hand held radio shack type microscopes, what i do to use it is use any thing you want first to get it so it's focused for you so when you look through at the magnification you want you can see through it clearly.. once you have it focused, take it and put it on the bud you want to inspect.. what i try to do is use the bud to hold the microscope still so it's not moving all over the place.. i simply put the part of the bud i'm looking at in the viewing piece on it and like i said, use that to balance it for you, let the bud do the work.. it takes a bit of messing around with for a few minutes until you get a feel for it, but once you do it's very easy to use and get a nice clear pix of what's going on with the trics.
