Fantastic image ! they are so nicely distinguishable !
Do you think that this type of overlap can be identified with phase contrast ? (of any diatom, not necessarily this one)

David Walker's article Diatom Pleurosigma angulatum - a versatile 'demonstration' subject. demonstrates the NA (Numerical Aperture) penalty that Phase levies.

I think you would therefore need a Phase objective with a very high NA to manage it.

Mind you, he also shows that using a Phase objective in Brightfield (and I imagine even more so with oblique) retains or at least pays a smaller NA penalty.

Amazing shot! You are diatom master of the Alboran Sea.

Many thanks Wes

I am fortunate that the diatoms in the Alborán Sea are photogenic

Map for those who might not have heard of the Alborán Sea or can't place it.

Hornblower fans might recognize some of the landmarks.

Hi Sabatini, not sure if you are referring to the Diatom or the fact that (to paraphrase a 'famous' american) I can see Morocco from my window!

Hello, sir.
Nice try.
I mean that beautiful diatom, it seems performs at the limits of optical resolution.
