|
|
I found some low-hanging mistletoe yesterday, and collected this egg. I'll be going back today with a ladder, and see what else the Easter bunny can give me .
Great Purple Hairstreak (Atlides halesus) egg on Mistletoe (Phoradendron), about 14X, Mitutoyo 20/0.42 w/135mm tube lens
Approx. 12X, Nikon CF N 10/0.30
I've been a little busy recently, so I have only had time to play with these eggs some more . . .

Beautiful! What optics? Any chance of a stereo pair on this one?

I used a Mitutoyo 20 with a 135mm tube lens, in part because I already had it set up and I wanted to photograph the egg before it hatched. This image is slightly cropped because there were streaks along one edge from the leaf curling slightly during the exposures. I just collected another half-dozen Atlides eggs, and I'm going to compare the images I get with my finite optics to those from my Mitutoyos. I'll try a stereo pair as soon as I have time - I know they can reveal additional detail to many viewers, but I've never been able to see the effect myself.

How sad!
I can't recall whether you and I have discussed this before. The most reliable method I know is to use a stereo viewer such as the Wheatstone Mini-Scope.
But even if you have two fully functioning eyes, it's not guaranteed that you'll be able to see stereo. I know one person whose eyes work fine, but he reports that there's nothing special about having them both open at once. Even looking at stuff on the table in front of him, he apparently gets depth from head motion and other cues, not from stereo vision. Presented with a stereo pair, he says the images lock up fine but nothing else happens.

Now I have the mug shots, I'll try some other perspectives.
