Hydrurus

Found this today and it reminded me that I had a few photos already.
The first is a branch, the second a close-up of the branch and the third is a motile reproductive cell.

Very nice images. I just read about this plant in a Google search. It has a quite interesting lifestyle. :)

I was wondering if your HMC objectives can be used for simple brightfield photography (without the hmc condenser). I have heard that there is a small loss in image quality . I would be gratefoul if you could post a realative image

Thank you in advance

1.) Dark Feild of Hydra
2.) Stentor

thank you very much.
Image quality seems without any issues.

And a last question . What objectives did you use for the initial photos? Are they modified by hoffman laboratories?

Thank you

Grant,

Very nice images! An interesting subject that I was not familiar with. In gathering a little more info I came across a short pdf that has a nice description (but the photo does not come close to yours :wink: )
