Re: Circular diatom

Hi. I removed the zoom from the video since it interfered with what seems to be some kind of internal contraction "12 o clock" of some sorts at around 9 seconds. Does anyone know what it is?

Re: Circular diatom

Nice, 75RR may be right: hard for me to guess at such magnification. If I may ask a question (not meant as criticism, but out of curiosity): why not a still image, since there is no movement? Thanks. Criticism is great. Look at the topic. It's probably an amoeba, not a diatom. I totally new at this...

Re: The microscopic investigation begains

In Norway, we have reports of dead microscopic crustaceans in our drinking water. No harm, but not something you really want to think hard about.

Circular diatom

Hi, In my pond water sample I have so far only found rectangular diatoms, no "live" round ones, until I saw this yesterday. Does anyone have any pointers on diatom anatomy? They are unicellular, and it could be interesting to know more about it's internal parts. 40x Objective. 10x eyepiece, afocal N...

Re: A very quick & easy water-mounted pollen stack

That's very nice! As I mentioned, I am new to this, and just wonder if there is a good reason to water mount the pollen. Would a "dry" mount work just as well? Just the pollen and a cover slip?
