Chrysoperla carnea

Post by AndrewC »

Shot with a 80mm El-Nik, then Nikon 10x objective.
Stacked with ZS PMax

Eyeballs were cleaned using an electrostatically charged needle tip - just lifted the dirt right off !

I started with a black background but with the higher mag shots with a microscope objective I find that the oof areas give horrendous halos so I switched to a pastel colour.

I started with this subject really to see how ZS would cope with 4 layers of wings - no problems - then I saw the eyes ..... I've got one more shot at 20x but i've used my ration for today :cry:

Enjoy - constructive criticism welcome :)

Most impressive! Electrostatically charged needle tip... genius! Ive spent much more time using an eyelash. Very nice coping with the wings indeed.. and the eyes look terrific. You can even see the ROYGBIV pattern in them. Bravo \:D/

Well fortuitous really, it is thundery weather here, I was wiping the needle on some nylon fabric to clean it and when I brought it near the dirt the particles just jumped off the eye and stuck to the needle - yeehah !

You know, you're getting good at this bug lark :lol:

Ok so HOW did you elecrostatically charge a needle :o !

Ah - posts crossed.
It can't be a very high voltage if you were holding it, even through the cloth it would have decayed quite fast.

Definitely something worth investigating. I see quite a lot of spark ignition devices which produce plenty of volts, mostly piezo but some battery.
Easy enough to charge up say a small paintbrush with something like that and a capacitor?

You can buy sensor cleaning brushes that do something similar - they are basically a soft nylon brush that sits on a motor to spin it and charge it. www.visibledust.com

Excellent photos!

If the humidity is low enough, It's easy enough to build up a charge of over a thousand volts on your body. We have all experienced the old doorknob jolt in the wimter.

Rigging an old empty piezo lighter to a hand tool sounds like a worthwhile progect. The insulated handle of the tool could be made into a capacitor by wrapping it in aluminum foil.

Maybe I'll give it a try. Our grill lighter is nearly out of Butane anyway.

Once again, really fine photos!
