Absolutely fabulous!
Thanks!
I was cleaning my apartment and found a screw-on teleconverter that came in a kit I bought when I first started. It would only fit on my Olympus 35mm 4/3 macro, so I tried it on. I strained out some extra zooplankton after filling this week's orders and have had it on my desk in a white box waiting for extension tubes. Hopefully the extension tubes with the 60mm will do a better job than this.
This is the concentration that goes into the bottles I produce, but I put it into a mason jar so I could shoot through the glass instead of plastic. The thickness makes it hard to focus all the way to the back.
The pods that are very visible are Tiger, Pseudodiaptomus and you can probably make out some Acartia. The little specs of white are Tisbe copepods and Rotifers.
