Thanks for the response.
I guess I was hesitant to post a log because I'm not even sure I'm approaching this the way I'm supposed to (ie. expecting it to be user error ) . Although, I guess an Open/Close should be pretty straight forward :=). Here is a log.

I do have the Dome Geometry settings entered. And the "Slave on Sequence Start" is checked. The dome does seem to be slaving to the scope/mount. However, the shutter opening is not quite in alignment with the OTA. In AstroMC there is a "sync to scope" function to address this - I was assuming the "Sync" button in SGP (Control Panel - Other - Observatory) is the equivalent?
I tried looking for more info on the Sync button in the Help file (and forum search), but I couldn't find info that would explain what I was experiencing. Again - it's quite possible I'm just not understanding how it is supposed to work.
