Thanks. That'll get me started. I'm taking a look on Ali now. And thanks Mike. Pardon my ignorance, but this is all very new for me. I doubt that I've used a microscope since I was at school (and rarely then), so not in this century, and not fresh in my memory. But let's just say the forum propaganda has been very effective on the value of a microscope, and with the costs to get myself started on this, I may even put the timegrapher behind the microscope in the queue. It should only be a month or so later, anyway, but I can't do it all at once. -
Sorry my mistake - I didn't mean 10X. The minimum zoom with 0.5X Barlow is 3.5X, and max is 22.5X. The following is from the Amscope manual. The "normal" eyepieces are 10X/20, to give a working distance of 165mm and FOV of 57mm at 3.5X and 9mm at 22.5X. Occasionally I need higher magnification to look at a jewel or pivot. Rather than taking the Barlow off, I bought some 20X/10 eyepieces - much quicker to change than the Barlow, and you end up with the same magnification (though the image is darker).

The Amphibia uses an armoured glass, that is, it has a metal ring on the inside around its circumference. If that ring is missing, it will fit but leak. The fact that you were able to push out the crystal using your fingers only tells me the metal ring was missing. It usually requires a crystal press or a very, very strong thumb and comes with pain in said thumb. Fitting a correct crystal w/o a crystal press is basically impossible. You can see me do it here!

Spot on — I just checked and yep, one of the balance pivots is smashed on one side. That would definitely explain the issue. Appreciate you pointing me in the right direction!
