Almost 1 year ago (26 Dec 2010) I posted this image; seems like these guys like cold water: http://www.photomacrography.net/forum/v ... 5ccd10bb4e
of a multi-nucleus Arcella sp ID'd and commented on by Ferry (thanks again).
I think I can see 10 nuclei in this one, images at 3 levels.

Nice images. I am curious though. Was he alive and moving when you got these shots, and could you actually see the nuclei as you were watching him, or only after seeing the images?
I have yet to see a nuclei in anything as I watch them. They seem to elude me.
Alive but fortunately not moving; the blue background caused by the DIC setup.
As to seeing nuclei: these images were sharpened but images seen through the eyepieces are always as clear/sharp as the final posted images, in fact I believe I see more detail through the scope.
DIC is really great for protozoa.

Yeah, I see the same thing, without DIC. The eyepiece view is always much sharper than anything I can get from the camera, which I haven't figured out yet apparently.
