Re: Wanted - Zeiss intermediate rings - and/or dic sliders for standard
. Wait, where is the male thread on this ring? There isn't one. Cylinder drops into nosepiece threaded hole and is held in position by threaded lens holder that screws into cylinder from the bottom. See arrow. This is the old type, I suppose we should present a selection of the available slide hold...

Re: 100x oil vs. 100x dry objectives
In my view not every subject merits high magnification and resolution, but when they do, it is well worth the 10 extra minutes you spend at the end of a session cleaning off the immersion oil.aristharcus wrote: ↑Thu Jan 14, 2021 7:29 pm
Anyway, maybe I must learn to use oil as a natural microscopy technique.

Re: A marine diatom with oblique lighting
You are managing to pick up some fine detail there. Well done.
Dragged your image to the desktop and ran Get Info on it - it says 115KB, so there is room on your side to up the resolution a bit.

I see on their website in both cases they're mounted directly to the coverglass. Have no actual experience of Diatom Shop, but would like to say that the blurb (which includes the above mounting information) is not as unique in terms of technique as is made out. That is not to say they are not well...

Agree, lovely diatoms and great detail. Do like the arrangement as well.
Must say you led me on a merry chase looking for 'Strictodiscus californicus' as my browser (perhaps sensibly) does not check scientific names :)

Nice selection of small diatoms. I must admit that I am more drawn to the larger ones as there is that much more detail to be seen. A big advantage of pond water and its denizens is that they keep and as you say reproduce. I have to replace my salt water samples every three days or so. Is your 40x a...

You don't mention the age of the child. Anything under around 8 years old would be a little young even for the stereoscope let alone the compound microscope.

One possibility is to inquire at a local university or institute as to who services their equipment. Perhaps even an in-house technician can help.

His repair PDFs have done more to raise the standing of a BH2 within the Big Four than anything else. As a Zeiss ...
