As identified in the Introduction, being able to line up the camera precisely is crucial. If the Pi needed to be moved to be worked on, or if the frag rack needed to be removed for cleaning, all pieces must be returned to the precise location that was established to ensure the camera angle does not change. To address this issue, we developed the Laser Assisted Guide (LAG) (Figure 22).
