Amphipleura pellucida, here a living one.
Hi, some time ago, we saw some great photos of Amphipleura pellucida shells by Jean Marc and others. Here are two pictures of a living one. First without polarized light: http://www.photomacrography1.net/images/Amphipleura_sCol_640.jpg (Zeiss Standard, Planapo 40/0.95; S-Kpl 16x/12.5; asymmetric Col...

Micrasterias thomasiana
Hi, here some pictures of Micrasterias thomasiana (is that right? Or are they M. denticulata?). This spring there were lots of them in the Sphagnum moss of my favourite pond... http://www.photomacrography1.net/images/Micrasterias_Gruppe_640.jpg (Zeiss Planapo 4/0,14) A view from the side shows that ...

Living diatoms, Synedra and Eunotia.
Hi, this group of diatoms lived in a small spring some kilometers from here. There's two species, the long Synedra ulva (somehow looking like a bundle of italian Grissini sticks ;-)) and couple of Eunotia sp. below: http://www.photomacrography1.net/images/Synedra.jpg Some details from the same slide...

Dear Wim, I didn't expect so many pages with botryococcus! :shock: Even a compound botryococcene is known. But if aqua farms with botryococcus will give enorgh oil? ;-) About the aberration problem one idea: If you use the Kpl (a 10x/18 W?) without additional relay lens and look through the phototub...

Hi Wim. ...The interesting thing about the 63X is that it is the objective with the highest NA. Higher than the 100X! But indeed it is more difficult to work with. I bet the working distance is very short! Thats right, but not really a problem. A disadvantage is that the image gets worse, if the obj...

Great work Jens. :D I have never viewed this type of algae personally but have heard the term "golden algae" used here and there. Yes I would say too that you have the use of COL down to an art. :D Hi Ken, thanks a lot :-) There is also a group of species called Chrysophyceae "golden algae" (with a...

Hi Charles, Thank you. Nice words, but I'm still learning... :-) Hello Wim, I like these fine optics very much, too. It took some luck to find both S-Kpl photo eyepieces indeed. Fortunately you can get even such precious things for the Standard system without spending thousends of Euro or US-Dollars...

Botryococcus, golden algae.
Hi, here two photos of Botryococcus. They produce a yellow oil, making the algae look golden. First an overview: http://www.photomacrography1.net/images/Botryococcus_40.jpg "Freestyle" lighting once more to get a nice blue/yellow contrast. (Zeiss Standard, Planapo 40/0.95; S-Kpl 16x; asymmetric Col ...

*** > Jens, > > Your 63/1.4 looks very impressive indeed! Well, then you like this image more than I do ;-) . Thanks anyway. It is certainly a good objective, but I prefer the Planapo 40/0.95 Korr. (with an 16x photo eyepiece) in most cases, because this way more possibilities to optimise lighting a...

Gyrosigma slits, once more
Hi, I'd like to show two photos of Gyrosigma balticum. First an overview. http://www.photomacrography1.net/images/Gyrosigma_balticum_640.jpg I took the darkfield condenser (Ultrakondensor) to get that kind of col lighting as Charles has used making his great diatom images. Unfortunately I couldn't r...
