Here are a couple of close-ups of the fork mount itself. I decided not to have a vertical up/down motion at the tripod pivot point, nor an azimuth motion - adds complication and potential wobble points. I decided to live with azimuth and altitude at the binocular pivot point, and rely on the up/down of my gas lift chair to cope with the different hieght position of the eyepieces.

By having the fork mount come out at 45 deg, I can point the binoculars sort of close to the zenith without getting caught up in the mount. I do move the binoculars forward on the central mounting bar since my gas lift chair won't go low enough. Though they are then quite top heavy, the mount locks well in place.
