That is beautiful. I have seen a lot of rotifers here, but never one with that center stalk sticking up. Do you know what that is?

Marek,

Once again, very creative lighting. I like the way the plant tissue is portrayed, as well as the rotifer.

Charlie,

Thank you for your nice comment.
By the way, what do you think about Carl Zeiss Jena GF Planapochromat objectives ? There was the oportunity to buy it at Polish auction, but I know nothing about the quality of these objectives. Are they comparable with the olympus s planapochromates ?

Thank you for any informations and best regards

Marek,

I don't know anything about their quality. An acquaintance (whose opinion I trust) was extremely impressed with a 25X Plan Apo he used, but that was the infinity corrected version.

The only East German Zeiss (RMS, 160mm finite) I have are a 40X and 63X, but of much older design (not "GF"). They are very good, but not exceptional.

Some of my local microscopy friends have those. There are very indeed very nice and often available at a very reasonable price.

Ecki,
Thank you very much for your additional informations. I have already 40 X objective. It is S Planachromat Olympus. It is quite good, but not so good as for example 40 X S Planapochromat Olympus. I'm looking for something similar to the last one (if about image quality). I've got already 10 X Olympus S Plan Apo and 20 X and 40 X S Planachromats but their quality seems to me not enough good. So the most important to me is comparison 20 X and 40 X GF CZJ objectives to the Olympus S Planapochromats.

Marek,

I really enjoyed this photo - thank you!

Any possibility of posting a photo just of the Sphagnum with the same lighting ?
