In the 3D view, the left and right are reversed

Not really reversed, right image is at right side and left at left
But not good to see with the eyes crossed

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)

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?

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...

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...

...plus figure out whatever thread that objective has to 3d print an adapter for that to the 210mm lens.

26mm x 0.75mm Nikon BD 210mm finite objectives, Nikon LU Infinites, and others

Pau, bigger version here. You'll be looking out of your ears if you get too close though

Thanks! it is spectacular, now i also see the cup shaped morphology of the protuberances.
The high res UV images are also excellent.

I just tried to screw a Sigma 56 mm f/1.4 lens onto a Canon 70-200 mm f/4 lens with the reverse side and got a vignette already at 135 mm...

This is typical of the Canon 70-200 mm f/4 zoom, also with objectives able to cover FF when paired with other tube lenses.

Gorgeous subject and pictures.
The stereo is awesome! Could you show it at higher resolution? (just for the pleasure )

At least in my Pentax the morphology is not so simple: despite that the general shape is, there are taped holes for bolts and recesses to fit a metallic pressure plate and a half tunnel to allow placing the axis and pinyon that engages the rack. Of course I'm not saying that it couldn't be done with...

Hi Betty,
The material in my case is PLA, I ignore if it's the best material but it works fine, it's biodegradable and in mines also luminescent

note: PM sent

Any recommendations how to overcome or improve the stepping size welcome. :) What's the step size you're getting? Do you use the microscope fine focus motor for stacking? I use the MicroMate attached to my different microscopes and microscope focus blocks driven by its own controller and software a...

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...

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

Nice picture, BTW

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
