Ahh Paul....well done and I should have realised myself.

For a start the trails are going in the wrong direction for Earthly rotation now that I look at it. And the idea of the camera slowly tiliting downwards makes sense... operator error strikes again!! I guess I simply did not tighten the tripod head enough. That image was taken with the tripod sitting on the pavers around the pool.
Ok...now that has been cleared up... I'll have a crack at those longer exposures.
Thanks for the fiddle RB

The stars are certainly much more defined and I can make out M7 alot more clearly!
