This collection is the best of Oblique High-Speed (1/4000) Shutter that I caught today. I wish they were sharper, but this is the best my 40-year old Plan Achromats can do.
This particular peritrich is quite a bit smaller than most I've photographed, but unlike so many others, it consistantly stayed on the end of its tether. Made photographing small changes in focusing easy.
