Auliscus sculptus

I was excited to receive a couple of days ago the 104 type diatom slide I bought from Klaus Kemp. Great to have all these types together in one slide!
Playing around a bit with color differential interference contrast, took this picture of the Auliscus sculptus with 100x oil immersion.

That's it for now, 103 more to go...

Anne, Sumguy, Dave and Jacek, thanks for your kind words!
I've decided this is one of my favourite diatoms.

Beautiful! Bravo! Can't wait for the other 103, lol...

Auliscus sculptus has long been one of my favorite diatoms too. Hope you won't mind if I say why, because it involves an important lesson I learned. Some years back a friend who moved away did me the favor of sending a sand sample from his new Florida home (near Ft Myers) in answer to my arenophile tendencies. When cleaning the sand, it very fortunately occurred to me to have a peep at the dirty rinse water before discarding it. Surprise -- the detritus was rich in diatoms, lots of very splendid diatoms! Among other wonders, it was my first encounter with Auliscus sculptus, which I found mesmerizing, and still do.

Thanks for posting (and the memories)!

Excellent, I wish mine would have turned out that nice.

Dear Nanometer, Kurt and Smokedaddy: you're welcome, and Kurt thanks for the interesting related story.

The first time I saw the diatom was on this forum , and I found it very different compared to any other diatom I had seen. With DIC it turned out to be a good match, the proper centering of the condenser was important for the result. A Canon Speedlite flashing through the collector lens of an original Leitz lamphouse was used, now my standard setup for DIC.

For the rest there was almost no postprocessing, the stack is compiled by blending 3 pictures together. Normal stacking did not work in this case.

Regards,

Walter
