Anything related to things that are too small to see them with the eye, and the tools used to observe them.

This space is quite general in scope - microscopes, microbiology, small component electronics, questions about buying optical components, etc.

Cyanobacteria (mander.xyz)

This specimen came from a slimy film of algae that grew in one of my algal cultures. I think that it is a Nostoc. Objective is 40x/0.65

They look more green than cyan to me.

That's not the cyanobacteria's fault, I think that it is mine, so thanks for pointing that out. In the post-processing I clicked on the microscope slide to white balance because the background seemed too blue. But now that you mention this I think that the bluish hue in the background was realistic and setting it to white removed the blue from the blue-green cyan. Without the white balance the color is more cyan:

Yo they look so lumpy. I never see fellas as lumpy as this.

They look chock full of microcystins just ready to fuck up a liver.

I didn't know about microcystins. Interesting molecules! I think this particular species does not produce them, but I won't eat them... at least for now. I might grow some edible algae in the future.
