Rocker box, side view
This drawing shows the rockerbox from the side. The mirror box is put inside for storage, to show the fit. Befor doing this, the trunnions need to be taken off, and stored in the rockerbox separately. The secondary cage slides into the mirrorbox, focuser pointing to the right.
Here the round dent in the side of the rockerbox is shown, which is the bearing for the altitude trunnions.
