Re: Some diatoms from Oamaru with 450nm light

Thanks Beats. Yes, I've seen plenty of broken ones, often as you mentioned with the central ring intact. This was the most intact one on this slide, and of the other few Allan's Farm strew slides I've got. It's a beautiful form, and I was really happy (and surprised) when it appeared as I was scanni...

Re: Some diatoms from Oamaru with 450nm light

One from a strew slide from Allan's Farm, prepared by Bernard Hartley. Brightwellia coronata . Almost complete - this is about as complete a one as I have seen in the slides I've got, usually it is just fragments. Olympus BHB microscope using 450nm light. 63x Leitz Pl Apo NA 1.40 objective with oil ...

Naming based on the slide label and to the best of my ability. Reduced in resolution for sharing here. 2023-12-17-03.0...

Re: Diatom dotting - again, but smaller

Beatsy, not quite the same contrast as yours, but this was my go using a 63x Leitz NA 1.40 Plan Apo objective, and 365nm light - https://jmcscientificconsulting.com/uv-microscopy-high-resolution-imaging-poroids-in-pinnularia-diatoms/ You still got all the details though, NA is the thing. Great resu...
