Impressed by Riks Fritillary butterfly egg results, I wanted to try a Nikon 10X microscope objective on bellows instead of the macro lens I would otherwise use for this magnification. A year or two ago I had tried a different 10X but was plagued by serious chromatic aberration, and gave up on it. This objective is much better for this use, and I was pleased with the results.
You get great resolution due to the large aperture, but it sure does take a pile of images combined to get any depth of field! (The top image is from a stack of 95 images and the lower from a stack of 102).
