| When the telescope slew finishes, check the SPY 1 to make sure that the domes are aligned with the telescope if no star shows up in the ACQ or Finder cameras. If the star is not in the ACQ window, go to the FIND window and do the same, then return to the ACQ window and repeat. | When the telescope slew finishes, check the SPY 1 to make sure that the domes are aligned with the telescope if no star shows up in the ACQ or Finder cameras.

Turn off the red LED and you are ready to lock the star. | Before locking the star, align the twfs to the red beacon, align the blue beacon to the labao, focus the labao and then focus the twfs as shown before.

| To lock the star, hit [MOVE] on the Main Tab of the Telescope GUI and then click the right star to bring the star to the ACQ hole. Turn on the TWFS tiptilt and DM servo on scopes that have it. Make sure the twfs tiptilt spots window show green dots that show the servo is tracking. Turn on the labao servo and DM AUTO on all scopes. All values should move to zero or near zero when the servos are on. | To lock the star, hit [MOVE] on the Main Tab of the Telescope GUI and then click the right star to bring the star to the ACQ hole.

| If the flux is low on telescopes on pop 5 or 4, there can be a misalignment of the IR starlight with respect to the blue beacon due to low elevation and the long distance to the lab. If this is the case, follow these steps to improve the flux. | If the flux is low on telescopes on pop 5 or 4, there can be a misalignment of the IR starlight with respect to the blue beacon due to low elevation and the long distance to the lab.

| On the obsgtk, set the beacon step size to 222 or 333. Click the Left button while watching the MIRCX flux plot or the STST image display. If watching the MIRCX flux plot, look for increases in flux after a click or two. Allow the DM AUTO function to adjust the blue beacon after each step by not moving the beacon out of the boxes. Remap the fiber to see if the flux is further increased when the labao has recentered the beacon. If using the STST, move the image flux towards the reference position set by the STS or CHARA beams. | On the obsgtk, set the beacon step size to 222 or 333.

| With the star aligned with the acquisition ticks, check to make sure there are counts on the TipTilt server or the white plots in the TT windows have condensed. On the Main Tab of the Telescope GUI, click [TIP/TILT] under the Pointing Servo menu. If this button is not pressed, then the green dots on the tiptilt windows will drift and eventually drop TT lock. The [STAR ACQUIRED] button on Cosmic Debris also starts the Tiptilt servo for all active scopes with one push of a button. On the Tiptilt Servo Control GUI, turn tiptilt [ON] for each telescope or use the [TT ON] button on Cosmic Debris to perform this function for all active scopes. | With the star aligned with the acquisition ticks, check to make sure there are counts on the TipTilt server or the white plots in the TT windows have condensed.
