Hmmm, I can't seem to find an option to force autoguiding before the Platesolving images are being taken (so I can set long settling time, to allow time for dome to catch up with scope).
Also, I'm not sure SGP is a supported option for external control of Dome slaving from within AstroMC/Foster Systems (not referenced in documentation). Hopefully someone in the Foster Sys Forums will respond (but its generally a pretty quiet place there).
