Clarification on observatory shutter logic please

Hi

I’m a little confused as to how SGPro deals with dome shutter closing when an unsafe condition arises or a sequence ends.

The SGpro help page says

“You should note that the observatory must be slaved to the mount to close as the observatory open/close is tied to the mount unpark/park event and can be setup in the Slave Settings for the observatory. Likewise you must also select to have the mount park when sequence completes.”

Does this mean that the observatory must be slaved AND the mount must be set to park in order for the shutter to close or does it mean that the observatory just needs to be slaved for the shutter to close at the end of sequence or when unsafe?

Many thanks

Steve
