The voyage of discovery that I am on, imaging the eyes of the spiders, keeps on delivering rewarding surprises. I never could have imaging that those deep black eyes properly illuminated, would reveal such a stunning blue/white internal structure. Or that they would appear almost human with an iris and pupil like center. Enjoy the beauty of our natural world.

Little Jumpers have always been different. As a pre-teen, I would find them on my window sill as winter approached. They would come inside from the cold, possibly to hunt the flies that also got trapped inside. I would even catch the flies and hand feed them to my 'pet' jumpers. I didn't dare tell my mom or brothers about them as they would have killed them. So maybe I saw something in their eyes, even then.

Laurie, Craig, Mitch, Eric, fpelectronica, Ecki, and Tim. My sincere thanks for all your gracious comments on my post.
Eric, as you probably already know, the 6.5x objective is used in conjunction with the Ultropak EPI illumination system. This allows me to project light into the subject from up above. However I did not use that benifit for image number 3. The lens is chosen for its magnification and good working distance allowing me to have my subject and diffuser on the microscope stage. I do not like to crop my images if I can help it and it is a nice intermediate mag between 10x and 4x.
