Both of the images below are 3 image focus stacks using the Helicon FB Tube on a Nikon 300 PF. Due to back issues, I have limited ability to get down "face-to-face" with these little critters sometimes, so using the 300PF has been a real help for me.
Baskettail Dragonfly
Orange Bluet Damselfly: Note the 3 small eyes on the top of its head called ocelli. The two compound eyes have 5,000+ individual light-sensitive "eyes" called ommatidia and detect movement 2x faster than humans! We have 52 species of Damselflies in MN and the male and female look different, so please excuse me if I get the ID incorrect! (Damselflies of Mn, Wi and MI by Robert DuBois).
