That last one is an interesting illumination. How exactly are you producing it? Is it a phase objective with a mismatched phase ring, or a phase objective with a classic dark ground stop?. It certainly looks like Navicula lyra to me BTW. Is the slide not labelled?

I'm having 'several issues' that I'm unable to solve but that's another story, so I may not be able to tell you my specific setup. I was told that any objective labeled 0.65NA or less would work with my Nikon 1.25 condenser in DK mode. So since I only have a limited selection of objectives I experimented using a Meiji Phase DM 40x/0.65 with my condenser set to DF.Cactusdave wrote:That last one is an interesting illumination.

The slide is not labeled. That being the case I simply tried to find a match in the Schmidts Atlas. That itself was an interesting adventure but I don't mind.
