I’ve tried the weather monitor using my Boltwood monitor.
If the mount is set to park the mount at the end of the sequence then if I start the monitor in an unsafe state then after 30 seconds it parks the scope but not the dome. This may be because the dome was not slaved to the mount and so the dome slave setting of park the dome and close the shutter when the mount is parked was not done. It would seem better to do this regardless of the slaved state.
I disconnected from the safety monitor and tried to reconnect and got this error as soon as I tried to connect:
Error connecting to ASCOM Boltwood OK to Image!
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
This doesn’t seem to be coming from the ASCOM driver, there’s no evidence in the ASCOM logs that any attempt was made to start the safety monitor.
