Here's a couple items that are available from Wemacro or you can assemble one from components from eBay. The ball heads are available in many sizes and inexpensive, this is a small size.

Best,

Mike

the stage allows me to lay several diffusers very easy

for a specimen holder I use a ping-pong ball, cut in 2 halves, filled with plasticine (to make it heavy) and taped back to original position ... the ball over a metal ring ... this is a very chaeap way to have tilt and rotation virtually in any direction and makes tunning the insect positioning very easy

Can you please give some more inputs on that specific image where you have placed multiple sheets as diffusers and then a plastic tube type on the lens? How do you determine how many papers/sheets to use?

Thanks

Thanks for this ping pong design I changed the interior to an old mouse ball, its heavy and being round it's always kept at the bottom.

I pierced the ball with a needle, covered the interior with some tape and hold it with some blue thing used to hold posters in the walls ( blutack )

One of my PVC creations:

It's somewhat obscured in this picture, but it gives you some idea. The platform is attached to a mini ballhead, that allows the angle to be adjusted in concert with the angle of the PVC piece onto which it's attached. The front legs ensure that it doesn't fall forward.

Anyone know what the long rails are in the post above, which seem to allow the 1/4 20 articulating arms to be screwed in?

Just noticed your question.

Generic t track from Amazon. A bunch of places sell it there.

Posing

I use pipe cleaners with either a pin or a small alligator clip on the end.

I've tried using stiff single conductor electrical wire with an alligator clip crimped on the end. It still vibrates a bit. It'd probably be ok for 1:1 or lesser magnifications.

Sorry.:?
The subject (beetle on the label) is always in the field of view, only the tilt changes. Unlike, for example, Novoflex.

Looks like goniometer without scale or gears.

kutilka,
interesting holder, although I don't think that it could be patented...similar positioning stages have been made for a century now. I have one made by Zeiss Jena around 1960-70.
