Björn, the "Big 4" stands for Zeiss, Leitz/Leica, Olympus and Nikon. How do all you BH-2 owners adapt your microscopes for temporarily polarising light, or other types of filters? I mean, you cannot prolong the light path by adding a sector and raising the head from the body in a finite system!? See...

Beatsy, Do you happen to have Dumonts No.5 or No.55 in your drawer for comparison? Otherwise your quest might not be completed yet?! :wink: Swiss made Dumonts are kind of a high-end lab standard, presumably for some reason. The tips of my needle-sharp #5 are the same as those of #55 that NU uses but...

Wow, that full resolution version really shows what the camera and componon are capable of. So obviously you got a lens that has not been maltreated before. :smt023 And I appreciate the background info on the beastie. (Same here: No problems in viewing the large version with Firefox 29.0.1 and Win 8...

Nice find Ken! I rarely encounter Mutillidae over here. Dixie has a much more favourable climate for them and insects in general. (Sigh!) Looks like a female Pseudomethoca . Somewhat a bit unlike some of the Velvet ants (wingless wasps) that I have seen, I am thinking maybe a juvenile? Being holomet...

-In my daughter's hair :mrgreen: :mrgreen: :mrgreen: Predrag, I appreciate your honesty! :D I was expecting something like that. I know lice infestations from kindergartens and schools. Becoming infested is not a sign of a lack of personal hygiene, so nothing to be ashamed of. Recently I drove by a...

Rik, Did you use your infinity Mitutoyo (which is in itself corrected) on a finite microscope with corrective projective or eyepiece and thus we see a correction of chromatic aberration where there was none, hence the red light on or towards the axis and the blue light away from the axis, a sort of ...

Thanks guys for your further input! The clear B+W filters that Craig has pointed to are just made for the purpose of protection of the front lens element, as it reads on schneiderkreuznach.com/fotofilter (B+W belongs to Shnyder-Krautsnack). Indeed Ken, the lens hood of this lens combined with its ex...

Ken, a nice find! Looks like the larvae of meloid beetles to me. They have a quite interesting natural history, many of them being parasites or parasitoids in the nests of solitary bees and wasps. I find them regularly in and around my neck of the woods over here in springtime. --Betty P. S.: I'm gl...
