Odds and Ends

#1 Post by rnabholz » Sun Sep 18, 2016 8:48 pm

Some shots from the last couple of days. The Lake Michigan slides continue to produce interesting forms. My best effort at ID, but always open to correction, confirmation or conversation.

First up is two different looks at Fragilaria socia. Two illumination schemes and two individuals.

****UPDATE**** I now believe these to be Synedra goulardi. I realized that the size was incorrect for Fragilaria. Sorry for the misinformation, ID is still an exercise for me.

They all look great. Something especially appealing to me about the second image.

As Jim said - pretty impressive 'odds & ends' you have there my friend!
I particularly like image #3 - the 'mother ship and satellites' - lovely imaging.

Nicely done. :D :)

Thank you Charles. For as much information as Phase can deliver, the colors can be a bit too much at times, so darkfield can have a certain elegance.

Thanks for commenting.

Thank you John.

I constantly see "space" images when looking at these diatoms. Galaxies, nebula, flying saucers.

Thanks

Very nice, Rod.

#1 and #2 look like high performance kayak to my eyes.

Very nice detail.

Like the shape of the Gomphonema minuta - such asymmetry makes it special

****UPDATE**** I now believe these to be Synedra goulardi. I realized that the size was incorrect for Fragilaria. Sorry for the misinformation, ID is still an exercise for me.
Given my knowledge of diatoms if you had told me it was a Gorgonzola I would have believed you. :)

All are, to my eyes, both very beautiful and show excellent detail. Thank you for sharing them.

I agree about the asymmetry, and this was a pretty big dog too.

Given my knowledge of diatoms, I may accidentally throw in some cheese nomenclature....

Thanks.
