Details:
Here was very cloudy so wasn't possible to see nothing, these images are microspherules or micrometeorites collected among 16 to 18 november and maybe (more likely maybe not)debris from Comet Tempel-Tuttle, source of the annual Leonid meteor shower. Fuji S2+ Nikon F2 coupled with a microscope.

Thanks for sharing these photographs. How does one collect microspherules from meteors?

There are several methods (searching on google), I use big tanks full of water placed in my garden and time to time I check the presence of microspherules passing a strong magnet at the bottom of the tanks..
This an interesting pdf:

The great problem is to be sure to not collect antropogenic products, look also here:
