Diatom ?
Re: Diatom ?
If the question meant "is it?" - it looks like a diatom. They are quite large at the west side of the pool and their relatives/colleagues remain fairly small at the east side...
If the question meant "ID ?" - following the Licmophora experience, once this one sheds its green-golden robe, the view of the striae will aid identification

Re: Diatom ?
Thanks Hobbyst46, I suppose it was two questions in one.
Have not kept the slide so no future installment to the mystery from that source. Perhaps I will run into another at some point and get a little more detail.
I wonder if what we are seeing is the process of reproduction by binary fission.

Thanks Francisco, found this:

Not sure how much light it sheds on the reproduction question

Re: Diatom ?
Thanks KurtM
your tip got me searching again and I think I found a closer suspect: Thalassiophysa hyalina
What do you think?

Re: Diatom ?
Now there's one I'm totally unfamiliar with. Let's look into it and see if we can tag this guy. And you only found one? What size sample and from where - benthic, planktonic, or ? Or were you in the marina scraping mooring lines again? Do keep an eye out for others.

Sorry I have no clue, just wanted to say its a great quality shot as the rest of your diatom photos. Keep up the good work! This is taken with 40/0,65 plan DIC?75RR wrote:Bumping this to see if I can get some confirmation on the ID

Re: Diatom ?
Thanks Wes
That 40x objective works surprisingly well for a 0.65
I would like at some point to try something with a higher NA but still dry.
Yes, it was taken using the Plan 40x/0.65 DIC slider and the designated 40x/0.65 Plan Objective.This is taken with 40/0,65 plan DIC?

Re: Diatom ?
True, I remember some other photos you posted (of Licmophora I think) taken with the same lens and they look excellent in my opinion. Occasionally you can find the Zeiss Jena 40/0.95 Apo objective on the German ebay for well below 100 EUR and I personally really like this objective. It produces a surprisingly flat field and the image quality is quite satisfying. It would probably combine well with your existing DIC setup for the 40/0.65 objective.75RR wrote:Thanks WesYes it was.

Thanks Wes, just making sure what it looked like!
It is 45mm DIN standard right?

Re: Diatom ?
Correct. It fits well on a turret with Zeiss West objectives. Combined adjustment of its coverslip correction collar, Optovar magnification and light color temperature/wavelength can yield remarkable detail for a dry objective.75RR wrote:It is 45mm DIN standard right?
