APPROXIMATE POSITIONING OF THE "NODAL POINT"
(Ref. Figure 8): Align the optical axis of the camera "Q" with the panoramic axis of rotation "R" using "CENTER" marking on plate as a guide, by loosing the knob "V" and
moving long plate "S" laterally .
(Ref. Figure 9): Align the longitudinal plane by loosing the knob "D" and adjusting the plate "F" until the front lens "T" is placed above the panoramic axis of rotation "U".
At this point, the position is already able to handle VR panning of landscapes or outdoor shots.
