Chain and cassette mechanism, and then the chainwheel with the 100 mm. This is middling clean.
Working my way into higher magnification. This is about 3x.
Going in a little further, this is 4x. That tooth isn't even close to the right shape anymore. I couldn't get closer.
The hole in one of the chain links at 4.2 x.
One of the cassette teeth at about 3x. I was having difficulty getting closer.
One of the spokes at 3.2x.
One of the front shifting wires at 4.1x.
I spent a while working on this little set screw trying to get the light and focus right. In real life it is 5 mm across. This one is 3.1 x.
This one is about 4.1 x. I spent more time fiddling with the lights trying to get closer than anything else, and I didn't want to get chain guck on any camera equipment.
This is part of the tire sidewall, and it's ever so subtly not in focus at 4x.
Part of the wheel rim at 4x.
Sidewall and wheel rim with 100 mm.
Here's the little set screw and the wire.
Next week, who knows? I'm looking carefully at every bottle of wine I uncork to see if there are any wine diamonds, and there are a few other things that have caught my eye. Stay tuned.
