Yeah Mick it can be a bit of a pain.
When you orientate the ota it should point in the same direction as the forks, not at 90 deg to them. The forks and ota should then point towards the SCP (your control panel should be on the south side as well). At certain times of the day/year the fork and ota will be rotated so that they are upside down and you will have to rotate the diagonal so that you can look through the forks. I'd suggest not trying to align on Sig Oct. Rather get it as close as you can to south with a good gestimate and then drift align. Once you have drift aligned then simply sync on a handy star, rather than run through the polar alignment routine of the LX200.
