Work in the daylight and rule out one thing at a time, this way your taking the guess work out out of things. Check your T-ring and tighten the micro grub screws to and look for play between camera and scope.
3 Maybe its just drive problems, not an expert at all but is PEC enabled?
4 dust, oil from finger or could even be glue off gassing resiude, have your try'd a sensor swab ? Have you done any flats to check this out, may give a clear image of what it is.

PEC was not enabled, will have to make sure i enable it in EQMOD next time.
After last nights more attempts, in which i took a few 10min subs, i have found more dots on the screen, which are bought out nicely here:

I havn't touched my scope's optics at all, so i am guessing the camera sensor may be dirty. I will try swabbing it.
The scope however, which i purchased brand new, does appear to have been used before i received it. It has dust inside the air compartments and the focuser looks slightly worn. I should have sent it back to Bintel when i saw it, but thought it would be fine. I hope the marks are not on the scope - else i will be disappointed.
I will also try the camera ideas.
With regards to PHD - i believe i have sorted that.
Had problems last night where it would track for a min or two, then Dec would start losing it and the graph would show dec climbing until it went off scale.
After playing with settings i found the Dec timer needed to be increased from 300ms to 500ms. Once i did this, tracking was very smooth.
Cheers all.
