Re: Bellows repair with new plastic dovetail inserts

A friend (and forum member) kindly did this for me with his 3D printing abilities and equipment after sending him the cracked nylon inserts of my two Pentax auto-bellows. I only did need to file them a bit manually and done. They work very well although a bit less silky moving than the original nylo...

Re: Oxycodone

I too see the weird parrot wth a bouquet of flowers.

I was sure that oxycodone was an opiod, not a powerful hallucinogen -with remote effects :roll: :shock:

Re: How to best photograph parasitoid wasp collection for ID

They look very nice and (I suppose) right for the task. Just I would place the scale bar at a more conventional place like horizontal at the lower or higher right zone of the image.

Are you going to do the job at Azores? if so, enjoy! they are wonderful islands :D

Re: rocking radiolaria ; conical path

Wow!
Excellent image stack, very clean and very good stereo effect.

Technical details, please. (all my, now old, attempts with dark field poyicistina radiolaria ended with lots of artifacts)

Re: Diatom: looks a bit like a SEM image

I like the way the pores actually look like holes instead of raised dots, for a change. Just a brightfield focus stack shot at 100x, then inverted in post. In fact they look like pores :D Excellent image and year beginning! (This reminds me an old post of mine https://www.photomacrography.net/forum...

Re: Unknown Leitz Orthoplan "intermediate"-lamphouse with high pressure bulb

Just guessing, but the only thing that makes sense to me would be an electronic flash, although the lamp doesn't seem to fit.
The only Leitz microscope flash devices I know are based on more conventional speedlites

Re: Hela Cells fluorescence DIC

Wow! Excellent quality...Even cancer cells can look beautiful. Immortality can be a bad thing :-k

Is it a fresh or a fixed permanent slide?

Re: Lichen spp

Mark, this is a most beautiful and colorful lichen cluster, very well imaged.

(I have almost the same film equipment: OM4, 50mm F3.5 and Coolscan 4000ED) :D

... According to him, the program does not recognize and/or command the microscope without recognizing a camera.
Does this make sense to you?
Not to me, but to Leica it likely does :evil:

Re: Debunking the high NA / coverslip correction myth

The image looks excellent and the technical aspect is most interesting. (And also illumination is exquisite, even more for small WD objective) I would like to know more data: - Is the objective refocused? (from the normal infinite design position, 1mm WD) If so, closer or farther of the sample? (my ...

Re: Stereo photo pairs microscope

The old Wild M5 has an optional phototube that can be switched between left and right tubes allowing for stereo pairs manually. Just for curiosity, the M5 is a nice observation instrument but I wouldn't recommend it for imaging

Re: Macro in Motion: A Tiny World of Lichens

Again an incredible macro journey congrats!
...but I saw some things I can't identify, like the "orange toothpaste trumpets". There's also an "alien egg..."
Maybe you're referring to the apothecia of the orange lichen and to what could be a black lichen propagule fixing on its new home
