Re: Copepod, Amoeba and Algae

Thank you all for your kind comments! Hello Hakan, they are all great. I like the Arcella best. I believe its a young Arcella gibbosa, when they grow older they partly loose their hyalanity. The blob bottom left of the sarcode is a contractile vacuole. By osmotic pressure the organism constantly abs...

Copepod, Amoeba and Algae

Here are some images from old photo sessions this summer/fall. The last one (Arcella) was a real pain and is hand-stacked. It was impossible to get Zerene or Helicon to do a decent job, so I hand stacked it from 14 images and manually selected the focus areas using the Zerene retouching module. Took...

Re: Unknown Organism Found From Tongue Sample

Looks like a piece of fiber. It can move due to movement in the fluid as it dries out. Does not look like anything (alive) I have seen. 8-)

Re: Olympus CX21. Your opinion?

I think 500 is a decent price. I had a CX40 which looks very similar. They also have infinity objectives and I paid $700. That was like 5 years ago. I would for sure go for infinity objectives as it is more future proof. It will allow you to upgrade to a more advance stand later if needed. Microscop...
