Improving Top-Stage Lighting Using a Smaller Aperture on the Lamp

I use top lighting for dark field images because I don't have a real filter holder. I've been experimenting with making a pseudo diaphragm for my top stage light. The question is, does a small aperture make my top-stage illumination sharper in dark field. I cut a 2 mm hole in a piece of aluminum foi...

Bacteria Swarm!

Bacteria quickly breeding in water where a large squash was immersed over the winter. There many kinds. The funny thing is I could barely make them out optically through the eyepiece but the eyepiece camera revealed them very clearly.

Are These Bacteria?

My algae culture had a big bloom of spores and almost all the larger protozoans seem to have disappeared. My lower two objectives reveal nothing moving. In the high power I see this. They seem to be about 75 microns in diameter. Are they bacteria? bacteriasharp2.jpg bacteriasharp1.jpg bacteria.jpg h...

I have some great specimens of algae with diatoms. Is it possible to preserve these? How? How do you use nail polish in making permanent slides?

Apparent Microbe Desert Actually Teeming

In medium power. my plant rooting water sample seemed empty of life except for scraps of dead matter. But when I went to high power, it was teeming. I think the organisms were bacteria not visible at medium power.

I got a sample from my son's salt water aquarium. The water was in there for about a month. The diatoms didn't appear for me until the biofilm built up.

It was in a closed bottle--but I received the original water sample from my son who has a salt water aquarium. It's been in the small bottle for a two months or so. At first it was overrun with algae harboring long worms. Then the algae produced multitudes of spores. The spores seems to have formed ...

I have water samples in small prescription bottles. Biofilms have been developing, floating on top. They appear to be made mostly of the spores of algae fused with a bunch of skeletons and fibers. I found many diatoms in it--many of them look like just the silicon shells are left. I made some pictur...
