Hey Lou, here's the full image scaled down: http://www.photomacrography.net/forum/userpix/5697_fluo_120x_06_full_1024_1.jpg and here's a link to the full res: https://imgur.com/a/h9ZZM8V Full res scale is 20nm per pixel. You see some irregularity, but I cannot discern the really cool structure, that...

I did an epi fluorescence image of the iridescent scales. This is done with blue excitation, an PlanApoN 60x/1.42 oil, specimen was mounted in immersion oil. I was trying out different techniques, this returned the highest resolution. http://www.photomacrography.net/forum/userpix/5697_fluo_120x_06_c...

Hi Boron,

this was the version with oiled condenser 1.4 top lens.

To quote one of my favorite movies: "I am an oil man"

Thanks for the replies!

@James
Microscope was a Oly BX52, PlanApo N 60x 1.42.
I used an astronomy mono camera, ZWO ASI 183MM Pro, 2.4µm pixel size.
First four images were taken with DIC HR, last two with circular oblique lighting @ 450nm.

Cool image!
My guess: It's upside down.

Whohoo a whoppin' 3.2x intermediate... That really cuts down your field of view though - but the detail is awesome!

I'd say: QED ;).

Hi Beatsy, great image! Just my 2 cents to the resolution vs. pixel pitch debate... OK, if you take Abbe, Raleigh etc.. the Sony Sensor eats 45nm per pixel at 100x. Let's take a wavelength of 400nm, so with a NA 1.3 objective and a 1.4 condenser, we can separate 180nm. So the 45nm seem way oversampl...

Stunning detail!
I really like the first one, looks like binary code, Matrix style.

Thanks for your answers! I think, the "double hairs" are translucent/refractive, and the light refracts on both sides, resulting in this effect. It was lit with two Jansjös, but from a distance through a paper diffusor, so this could certainly also contribute, givin some kind of direction to the lig...
