Bad stuff happens... Sequence Generator Pro supports different kinds of recovery depending on your gear and situation.
When SGPro encounters an error, the default behavior is to end the sequence and perform end of sequence options for your gear (park, CCD warm up, etc). Checking this option will provide basic recovery in that SGPro will only abort the current target and attempt to move to the next. This can be helpful if there is a chance that the view of the current target may have been obstructed, but the sky is still (mostly) clear. Click here for more information.
Sequence Recovery Mode
This type of recovery is designed to resuscitate a sequence that has failed in some way... whether that be loss of a guide star or failure to make a precise pointing movement. Taking a minute to understand how this works can help prevent a loss of valuable imaging time due to a mishap early in the night. Click here for more information.
Restart on Safe
This is exactly what it sounds like. If you have a safety monitor (weather monitor), SGPro will listen to it and shutdown your rig... park, warm up the CCD, etc. This recovery option will then restart the sequence and wait for your safety monitor to give the all clear.

Capture Calibration Frames on Sequence Failure
If your luck has run, but you still have a bunch of calibration frames to grab, enable this option to grab everything it can before shutting down. Note that SGPro will park the mount and observatory and, for flats, enable your flat box. Click here for more information.
