This is one of my first attempts to use the 1950 Lomo OI-2 darkfield condenser substage a Nikon optiphot. It's a wet condenser and I use it with glycerin. Sometimes it works very well, bright subjects and a nice black background, but often the field is uneven, with bright/black areas and with black/black areas (or even bright/bright spots). I move the subject around to a good contrasty spot... With 40x there are often nova-like halos.
Anyway, it's much better than what I got with a patch stop in an abbe condenser.
In two of the North-Western pollen grains it shows where the black/black area starts.
