Ok a bit of an update.
I have changed the min move in X to 0.02 and max to 2.0. I took off the PE and installed a flat line. Then I ran guide exposures for 1 second but found that did not have bright enough stars so I made it 2 seconds. The guide graph is a lot smoother now generally in RA. So I am getting somewhere. Stars are round at 10 minutes too. I have a bit of wind down the observatory tonight so I cannot go much further than I have now. I will report back once the camera comes back from the States.
Thanks so far for the help guys.
