Just so I’m clear (as this seems to be a sensitive issue). I own a new MX+ mount and use TSX to model the mount and take advantage of very accurate slewing. If I buy/use SGP, as I understand it, you cannot use the Auto Centering function as it requires a sync command to be issued to TSX (which I take it is forbidden).
So I would be left with connecting the camera temporarily to TSX (Camera Add On), to perform a closed loop slew to center and frame the target. Then, I would reconnect the camera to SGP and start the sequence on that target.
Is this correct?
