Thanks Will and NU. I was so hoping I wasn't fooling myself. I thought I could see it right away, during processing. There are fine details now that I just was not resolving before due to the crud on the lenses. NU, remember those coverslips? LOL, this is exactly what they looked like, like a fine mist of oil had gotten on them. Of course, the trouble was, I could not find out how to get inside the arm to clean any of it. It turned out that Nikon uses glue to hold down the cover that hides the screws that hold it all together.
Here is
a page with lots of images of the operation and what I found inside, for those interested. Kind of pretty in there too.
The Trinoc head is another matter. Easy to get in to, but impossible to clean. It just has too many little levers and slides for anyone but a technician to attempt disassembly. I could get it apart, but it would never go back together. LOL I will have to find someone who could do it.
