Actinocyclus subtilis

#1 Post by 75RR » Mon May 04, 2020 11:00 am

Planapo 63x/1.4, DIC, 65µm, stacked in Photoshop, Marine sample, Alboran Sea.

Now that they are letting us out and about I went down to the port and collected another seaweed sample.

Always seem to be plenty of diatoms to be found when one picks some up with tweezers and taps lightly on a slide.

I've been curious about your strategy to sample and photograph diatoms. Thanks for giving us some hints!

Superb !
April-May are the best for seeweed on this side of the sea, yet the beaches are still closed...

Cool, I like these very much! Great work.

Have you considered doing permanent diatom slides?

Obviously a fine lens, being used well
... with beautiful results.

Science and Art in harmony.

Now there is a scary thought. I do admire those that can make them!

Lovely diatoms, and images of them. Well done, sir.

Try tapping harder and see if you get even better results? 8-)

Tried that, it tends to dislodge grains of sand that impede the cover slip from laying flat enough to use the 63x.

Those of us who are 'fortunate' to have one, know how finicky they can be ;)

Great looking diatoms.
They're easing up access here a bit starting tomorrow, so I hope to get some salt water samples this week myself!
