Guider calibration must be done before guiding and must be redone after any change of the guider optical train (e.g. guider camera rotation)

To start the guider calibration, run Invoke-WebRequest "http://localhost:18700/SKSS_StartGuiderCalibration"

Once started, the guider calibration is doing a “L shape” to calibrate the guider speed and the angle.

During calibration, callback events are fired by SkySurveyor and displayed in the REST Callback Listener Powershell console (Bottom left)

To watch the video tutorial you can download the video SKSS_StartGuiderCalibration.avi from and use the Windows Media Player.
