Have just purchased a 12 mm illuminated reticle eyepiece with matrix grid, so we can see more exactly what is happening with any movement and hopefully correct it and improve the length of time we can shoot.

G'Day David,
The best way I know to troubleshoot those sort of things is to use the drift explorer in K3ccdtools... I notice you don't list a webcam in your signature, so I suppose you don't have one, but if you could lay your hands on a webcam and K3, the graphs in the drift explorer will tell you a) how good your drift alignment really is (very quickly) and b) whether you have any periodic error or tracking rate errors. Just a suggestion
.
If want to give that a go, and haven't used K3 before, we (myself, 1ponders, and probably some others) can try to help to steer you through the drift explorer by remote control... it might not be as easy as showing you in person, but we could have a go!
Al.
