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...

Re: Galanthus
Very nice!
You're resolving the cellsStill the texture of the flower pedals is breathtakingly beautiful, really looks like glittering snow/ice.

Re: Debunking the high NA / coverslip correction myth
Hi Macrero, May I ask again an unanswered question? - Is the objective refocused? (from the normal infinite design position, 1mm WD) If so, closer or farther of the sample? (my bet is that it is refocused closer although farther would be more desirable) How much? In your image I can see very little ...

Re: Debunking the high NA / coverslip correction myth

Re: What are these?
Without knowing anything ... teleconverters? Never mind - that would need a bayonet at the other end too. This is also my bet: teleconverters devoid of the rear male bajonet: at the second image we can see that they're acting like divergent lenses. Although teleconverters could work I've never seen...

Re: Kinoite on Apophyllite from the Christmas Mine
Nice sample and picture!
Please note that the stereo is parallel type (the one I prefer but not the more usual here that are to be seen with crossed eyes)

Re: microscope lens 10x
52mm (male) to RMS (female) adapter. In this case no need of two steps
This is pretty common at ebay and other sites
No idea about your zoom convenience. What camera do you use?

Re: microscope lens 10x
Yes, almost 100% for sure this is RMS, full corrected and computed for 180mm tube lens like the UIS series If so, the magnification on sensor with a 100mm lens focused to infinite would be about 5.55X. Being designed for 22mm FN, likely it would not cover the sensor with good quality up to the corne...

Re: ultra macro suggestions beyond 10x -- cheaper but ok objectives to play with? Sony aps-c
This is not the BD version. Infinity non-bd CF objectives have an RMS thread. The infinity CF BDs use an m27x0.75 thread. Normal LU plans use the same 25x0.75mm thread as other eclipse objectives, that should be fixed on the list. When reading the original post (I now see that it has been edited, a...
