Generally restarting everything is the best way to fix major issues.

• Begin by killing the GUI and reopening it.

• Next, try restarting the GUI computer

Killing the GUI or even the GUI computer does not require you to stow the telescope. All telescope telemetry and controls are stored on the TCS computer not the GUI computer

• Finally, you can restart the telescope computer by turning off the switch labeled Tele Power and turning it back on.

If at all possible you should stow the telescope before doing this. When this computer is restarted it will assume the Telescope is at stow
