Thank you for your appreciation! 🙂

For high-magnification macro images, I use a self-made, large, heavy and robust device with fine multi-directional advance, on which I mount the necessary accessories.
The camera used is the Sony a6300, but the accessories are mostly on Nikon mounts (with adapters), with no electrical contacts that can transmit information.

Everything is adjusted and set manually, ISO at low values (100-200, rarely higher values), aperture usually closed at f:16, or fixed/native on microscope lenses. Lighting preferably with continuous LED source (one, two, three sources, diffuse or spot). The camera is on a tripod or on a stable stand, the exposure is adjusted to the given situation.

So, the first image is taken with a microscope objective mounted on an extended set of macro tubes, at ISO 200 and exposure of 1/80s, with a single diffuse LED light source.
The second image is taken with a Sigma 90mm macro lens, ISO 400, f:16, 1/2s, two LED light sources focused from some distance.

Thanks for the detail! Most interesting.

One last question: In the original post you indicated 240 stacked shots for the first picture - how many did you stack for the second one?
