Sequence Generator Pro allows for automatic (in-sequence) restart of event frames that have errors in auto-guiding.
To use this feature, you must be using PHD2 auto guider.
Settings for this option can be found in the control panel in the Auto Guider Tab.
If this option is checked, the frame will restart if the guider error is reported above the user defined value above. The frame will not restart until the guider error falls below the settling distance (also defined in the Auto Guider Tab).
When a frame restart occurs, an event notification will be generated that shows the relevant details (more information on event notifications here).
