This close-up shows the somewhat difficult-to-photograph tertiary's
collimation mechanism. To the left and right of the plywood mirror-holding disk you can see
the pulling screws placed in the plane of symmetry. At the middle of this disk, the top
pushing screw, made of brass, is visible. Directly to the left, a short length of an
unnecessary, now removed, brass centering rod can be seen, and left of that, barely visible,
the lower pusher screw.
