↪ Comments			almost every mirror needed to be manually moved into position. This task was made difficult due to the poor quality of the video feed which was constantly scrolling the image of the AOA. AOA exposure also needed to be set to 1/500 to catch mirrors. AOA mirror positions may need to be updated to catch 11:1 reference spot.
