282: 125 _microns_????? That's not a close-up, that's a micrograph!
I'll be chomping at the bit for that hint!


I don't know if this is much of a hint, but what you see in the photo is not
the whole object, you are looking at a cross-section of something. I'll try
to come up with another hint in a day or two if no one gets it.

Btw, thanks to Badger for sending this photo to me.

A pleasure.

Badger.
