If you disable watchdogs (and I think its a bad idea) no error will be checked in your guide during exposure.
If you lost the guide star and is not possible to regain it next exposure will start again without guide stable … this is why I tell you to use watchdogs. Just increase the error and not use the lost star watchdog if you trust your mount.
Dithering will check again for the guide settling in any case !
If you not have watchdog sequence will continue until end, if you dont dithering and dont guiding !!
If the sequence finish with error from OnTheFly is just end all.
If you have guiding watchdogs enabled, Voyager will be retry to acquire guide stars for 3 times and recalibrate for so many times to try exit from empass … but if the sequence finish with error you must restart manually.
If you want to manage errors and retry use the DragScript. This is a simple dragscript to manage with error 3 target:Please post here your DragScript - #10 by Voyager
You can also do something more simple in DragScript for one sequence just using a repeat block with inside the sequence block until the time you need. In case of exit from sequence before of this time Voyager will restart the sequence.
All the best
