Thanks guys,
Dennis, it was simple really. I changed the setup from a side by side saddle plate system to a piggy back system. I made sure that the rings holding the main scope were as far apart as possible with the large Losmandy plates. I borrowed a set of rings from a mate as the ones I was sent from a supplier were the wrong ones. These are now being replaced and I expect to see them some time this week.
I also have replaced the DMK with an Orion Star Shoot autoguider and am using a diagonal rather than using an extension tube.
I also ensured that I taped up all the cables to the saddle plates to prevent the weight of these causing any further flexure problems.
David, you only really need to use a 17" monitor. 80cm monitor is going a bit far. I am not surprised they are a bit pixellated.
