Thank you Jeremy for the clarification, as I was confused about what's now true and what's outdated information. ?

Congratulations Gareth, nicely done.

because people ask me for footage: 90% of this is shot with the 20mm, the two close-ups are with the 35mm:

last lowering to 1250€, otherwise i keep the lens ?

Used Gossen Luna Pros can be had for 30-50$ and are great, and you can calibrate them, should they be off.

lowered to 1350€

I bought one in excellent condition a few weeks ago. The viewfinder is surprisingly nice. I'll have to 3D print a bottom sleeve to round the corners a bit, as they dig into my hand, when i try to cradle the rather heavy camera, and focus the lens.

Polaroid Tour:

The two doublets in the eyepiece is the Plössl eyepiece itself probably. https://milwaukeeastro.org/beginners/eyepieces.asp

Here's a simple relay lens with two achromatic doublets. Left end pics up the image from the focusing screen, right end focuses the image in front of the eyepiece, which then picks it up and magnifies it. In such a setup, you can space the two achromatic doublets further apart, without the relayed image getting out of focus as long as the focusing screen distance stays at the focal point of the first achromatic doublet, and the eyepiece at the focal point of the second achromat. I hoped the viewing system on your ACL was as simple as that, but by what you describe, the beams are not collimated in-between. In these more complex cases I bother an optical engineer, which I am not. Sorry I could not help ?

As long as the rays are still collimated in that portion of the viewfinder, so not converging or diverging, this will work. You can try this by pulling out the original viewfinder by a few centimeters while keeping the axis (making the optical path longer) and check if the image stays in focus. If it is still in focus, you're good to go ahead with a prototype. The image is mirrored twice with your add-on, so no image flip. You can also use a prism, to ensure the angles meet the close tolerances, or two mirrors, like you said. Enhanced Aluminum or enhanced Silver mirrors have an extremely high reflectivity, the light loss will be minimal.
