If you are using the STED as a confocal you may from time-to-time notice that the controls for scan field rotation are not visible in the software or on the control panel. This is because the microscope has been used for STED and scan field rotation is disabled so the illumination and depletion lasers remain aligned. To regain control of scan field rotation you need to quit and reopen the software and turn off the STED switch when you see it on the splash screen.
