Nikon 40X 0.55 LWD
The lens looks like this: https://i.postimg.cc/qvNSdmyn/Nikon-40-X-0-55-LWD.jpg It slides cylindrically, setting that way the thickness of the glass that should be placed above it. That has the option to set it in the range of 0 to 2 mm. It requires a tube lens of 160 mm. As you can see I`ve placed ...

Re: qDslrDashboard & Zerene Stacker compatibility
The only thing that remains is to connect the second of the 2 HDMI ports of my graphics card to my TV screen, thank you Rik.

qDslrDashboard & Zerene Stacker compatibility
Halo everyone, I have a D850 and a new PC system and I`m trying to get qDslrDashboard and Zerene Stacker to work sideways but when I`m projecting the image from my camera in a dedicated monitor ZS cease to respond. I thought that while using the shortcut keys (ASDF) the rail will move as normal, but...

Re: Equations
In my aims, it is highly possible to play an important role except for the equations the lists containing step sizes too, beyond the list in Zereene Stacker & the Weelmacro one do anybody has in mind any other one? Rik, the second equation is the base of Johan J Ingles-Le Nobel calculator if I recal...

Equations
I am at the starting of a very ambitious project that might take me a lot of time and effort. The only thing I want from you is to contribute your methods/equations/formulas you use to estimate : The magnification The step size Also the DOF ones [if you believe that applies in our kind of microphoto...

Question about capturing small insects
Almost all of us have seen the fruit fly portrait in Zereen`s site, where they sow us how to retouch hairs using Zereen`s features. I have the rig but I wonder how they could be able to catch and handle such a small subject. The irony is that, due to the COVID 19, nobody is allowed to come close to ...

Sigma life size atachment as a tube lens ?
Do you think it will work in an M42 rig? I found this in the net ; http://www.photomacrography.net/forum/userpix/5216_Annotation_20200101_110045_1.jpg I have the "life-size attachment" and the adaptors to reduce the diameter of it from M52 to M42. I assume that since I`ll be using less from the diam...

A question about combining methods of macro
I wonder if I place a lens reversed and exactly at its working distance, I attach an objective, would the reversed lens act like an eyepiece to the objective. I mean will the magnification of the reversed lens multiply the objective's one?

A more promising application is to put a filter over the lens to cut that violet light (light yellow usually would do) for detecting the fluorescence of the sample. I suppose you mean to put a yellow filter behind my objective otherwise how can I interfere a filter between a microscope objective an...

Pau, we are posting at the same time. I know the danger, so I`m enclosing it in a pipe sliced as to light only the specimen. Inside the pipe, I'll place a metal sheet for reflection towards the specimen and for protection towards me. I don`t think the reflection on the specimen would have enough pow...

Question Abought UV light.
Does anybody know if the UV light will harm my sensor?
I don`t expect to take advantage of the UV light as I don`t have the proper sensor since I have thought a 375 nm lamp, I`m thinking to experiment with some affordable lenses.
