Re: What camera adapter for trinoclear microscope

There is some thing in the microscope port or into the 0.35X adapter that is vignetting the image. More questions: 1. (again) Is the round image field as seen through the eyepieces bigger, similar or smaller than the camera round image field as shown? Observing and imaging a ruler is very useful for...

Re: Fossil diatoms in their natural habitat...

...in their natural habitat... :lol: :lol: =D> Although they have been extracted, their habitat is the diatomite stratum Very promising raw material Very interesting! This is definitely a case where I needed to see the full resolution image to make sense of what I'm seeing. I can't agree more

Re: What camera adapter for trinoclear microscope

The question now is which adapter I should use from camera to microscope to obtain the same field of view and focus through the camera as with direct view. Is the image too big or too small when compared with the eyepieces field of view? Please clarify this point Because the sensor is rectangular a...

We can't host this kind of copyright protected stuff. I would suggest to put the pdf in a remote folder (dropbox, google docs...etc) and share the link privately. I understand this to a degree.

Re: Soy Sauce landscape

Very nice!
The crystal itself is almost for sure of common salt NaCl. The other components of the complex mixture just produce flavor :D

Re: Glut of Rodenstock Apo Rodagon D 2x

Seems weird but the Apo Rodagon D 2X is optimized for 2X when reversed (and for 1/2x when "normal" mounted), did you know?

I haven't used it for some years now but I also remember preferring the 1X model for my 18Mpx APSC

Re: Wasp, Nuthin' Fancy

On second study, I'm not seeing a bi-color mandible at all. What's happening is that the mandible on the right side (critter's left) is tipped upward/inward at a very unusual angle, exposing a darker structure that would ordinarily be hidden behind it. To me it seems broken, isn't it? Anyway, a ver...

Re: Hoffman Modulation Contrast (HMC) for Leitz Orthoplan?

In a similar way as Phase Contrast, HMC needs dedicated objectives with the modulation plate built in* (and the matched HMC plate at the condenser). Do you have such objectives? Oblique illumination techniques can deliver DIC like relief contrast with normal objectives, there are many threads and po...

Very nice!
Still the texture of the flower pedals is breathtakingly beautiful, really looks like glittering snow/ice.
