here's another diatom I like a lot. Extern lighting and this time the SPlan Apo 60x/1.4.
The most interesting thing was, when I examined the center closely, it was revealing some dots with defined lit and dark side, that each measured around 300nm in diameter. Should be close to the resolution limit of classic light microscopy?
