So the collimator showed up. The overall build is very nice. Nice materials, etc. Seems very sturdy and secure for alignment, etc. Optics all look clean.
The eyepiece cup isn't perfect, but works fine (a little prone to lose position).
The Siemen star is crisp. Very sharp. I'm seeing super fine resolution in the center. So the target is high quality. And very clean.
Testing a few cameras, things are looking good. So I am excited to have it and to be using it.
One problem is that the threads on the eyepeice for focusing are far too tight, at least on my sample. To turn the tube for getting precise focus means using two hands, torquing the whole assembly out of focus, and having to break loose the threads at a larger scale then needed for fine adjustment. I spent a few rounds of filing the threads (one part looks to be 3-d printed nylon or such) and overall diameter down to get a secure but functional focus action.
I wrote to Matt at Reveni about this and he said it is supposed to be this way (super super tight). So either my sample as off, he didn't understand the condition I described, or his idea of achieving fine focus and mine are radically different. Considering that there is a setscrew for the focus setting, I don't see the need for tightness that destroys alignment and isn't functional. Oh well. a little work and all is fine.
