This is truly amazing. I thought that such detail was only possible with an electron scanning microscope, not with traditional optics!

Wow, the 20x images are stunning!  Is the rainbow color on the compound eyes fixed, or caused by iridescence or some sort of prism effect?

It is fixed, you can see it with your eyes. I believe it fades as the eyes dry out, so it is not fixed forever.

I really don't know why it is there and I was surprised to see it.

Bob, I was intrigued by the apparent added amount of detail when the 200 Micro is used as a relay lens. The early 200 Micro-Nikkor was, as I'm sure you are aware of, regarded as the least satisfying of the trio 55-105-200. However, no one would believe this based upon the evidence presented here. Thus, do you have to remove lots of CA and other artefacts, or are the image (in principle) straight off the camera?

The images are processed using contrast, saturation and unshared masking. There is no CA removal per se. In particular, I use Octave unsharp masking.

The AiS Micro-Nikkor 200/4 is a big improvement over the old Nikkor 200/4 presumably due to the improved coatings. I also got much better results using the reversed Raynox lens which requires a significant number of extension tubes which I flocked to mitigate internal reflections.

The problem here was the "hot spot" in the first 20x image which may be due to direct reflection from the eyes, since change the relay lens to the Micro-Nikkor did not eliminate the hot spot.

I no longer use the older Nikkor 200/4. The added value of the Raynox lens with extension tubes is that I can adjust the magnigfication by reducing the tube length and hence get intermediate magnifications from the objective ratings. If you notice the first image is at 3.9x using a 5x objective
