Swampwalkler - with a very powerful Loupe and a MINT Best Tractor.
Using these tools it is very simple, since the lines on the tractor are extremely fine and misalignment can clearly be seen
But it does require a very steady hand and an extremely good eye - and lots of light
I had a friend set mine up, since he has much better eyesight than me.
I verified his efforts using an extremely good 150mm macro lens on my camera and I could clearly see the alignment was correct in the photo
A lot of trouble to go to? - perhaps, but the sound quality is excellent.
Regards...
