With the passage of a cold front some nice (below 15ºC) temperatures slowed down the life and was possible to take shoot sequences of the asilidaes.
This one is a stack from 8 shoots, with Canon MP-E 65mm @ 5x and f/4, taken handheld as it was landed in a stable wood much better than the usual leafs.
It has some out of focus rings, and is no match for studio stacks with microscope objectives, but is a live thing and the resolution is enough for detail at larger omantidia.

Excellent! Striking illustration of the difference between small and large ommatidia in different parts of the eye.
I assume that "out of focus rings" means that some of the focus steps were too large. I will have to take your word for this -- I have looked closely but at this image size I cannot see them.

Thank you, is very good so much positive feedback about the image
This one was stand for about 2 min wich allowed 7 sequences, the sequence at f/3.2 wasn't as good as f/4 as the focus steps were even more noticeable, there is a diagonal composition I will upload after a careful retouch.
Exactly, by "focus rings" I was refering to focus steps, I send unsharpened tiffs to zerene stacker and sharpened in GIMP after the final result, I think the sharpening minimized the focus steps parts, but i'm not sure if this workflow is the more recomended or if it's better to send sharpened tiffs to zerene.rjlittlefield wrote:I assume that "out of focus rings" means that some of the focus steps were too large.
