My Arachnoidiscus
My Arachnoidiscus
This is my Arachnoidiscus from a sample sent to me from Edmonds, WA. Sample was cleaned and mounted in Zrax about two years ago.
The Arachnoidiscus is one species of this type slide: The view from the B&L Stereomicroscope at 4X: One shot taken with a 25X Zeiss Neofluar and Canon Ti3 One shot taken with a 100X Zeiss Neofluar and Canon Ti3

Whoa! I'm sold. Incredible images. I almost have all my goodies together. I can't wait to get started. Many thanks, Charles. You're doing such great work. Keith

Lovely oblique/brightfield images. I know DIC is often the desired method for these subjects, but I still much prefer this type of shot. Thanks for sharing.

Re: My Arachnoidiscus
I agree, I like this kind of method too. Perhaps it is because I don't have DIC at present, though I used to, but it does seem to work nicely with diatoms.
This (below) is Arachnoidiscus japonicas, from an old Watson slide.
Re: My Arachnoidiscus
Misread your opening sentence. Thought at first that the slide was by Edmonds.
Only now did I realize that it was yours! Most impressive work, as can be judged by your image of Arachnoidiscus.
Consensus seems to be that your image is Oblique, it does however look like Brightfield to me. Perhaps you can let us know.

Nicely imaged grouping photomicro, what objective did you use?
What is the story there? Upgrading to an infinity system?Perhaps it is because I don't have DIC at present, though I used to ...

Re: My Arachnoidiscus
Used a x20 objective. This is VAC, or variable amplitude contrast, which is easily made for any stand.
In terms of a story...yes there is. I had too many stands, though my main one(s) were Zeiss West, I was frustrated over time with de-lamination. So, I got rid of all my stands except one make (but with one other for sentimental reasons) which meant losing all the Zeiss, and DIC capability. In truth, being the initial Zeiss common slider system, it was never as good as the sort of thing we see now.
The make I am sticking with is Nikon, though by chance rather than planning, I have 160 and infinity !
