Focus: Aligning the secondary and tertiary panels

Measuring/adjusting the secondary/tertiary with videogrammetry:

Place reflectors on each panel of the secondary/tertiary and then take pictures using videogrammetry.
Back fit for the camera position and then find the position of each panel (angles only).
Adjust each panel by turning the vertical adjustment screws at each panel corner.
Iterate the measurement and adjustment.

Results:

Secondary panel alignment .5 mm rms
