- | Go to a computer anywhere to check the beam remotely at the telescopes. Check Vacuum Monitor that the vacuum is below 20 torr. Open telescope gui from pull down menu. Click TV [ON] to open the camera window and click [M10AL] to change view to the M10 alignment view, click [M7 open] to open the M7 mirror cover. Center bright spot in beam on the black reference spot. You may need to adjust the IRIS or the TV brightness to see the bright spot well. [BEAM] cycles the iris from open to closed and gives a good idea of where the center of the spot is. To adjust the position, use Pico 2 to select, for example, E2M10 → [MOVE] (use large steps ~ 100) * Note that the up, down, left, and right buttons do no correspond to the actual directions the spot will move. When the spot is centered, click [M7 close] to close the mirror cover * click TV [OFF] to close the window | + | Go to a computer anywhere to check the beam remotely at the telescopes.
