BTW, PE on my specimen of EQ6 PE was around 23 arcsec pp. about the same as yours (minus wobbling, if there is one)

The alignment was fairly close but not spot on. I did a quick drift alignment and all seemed OK. The thing that gets me is that the drift varies from one frame to another with a few being fairly good. I can't think of anywhere where a wobble could be generated and everthing was tight.
One thing that I did forget to do was re-balance the scope between a quick observation period to show some people the moon and imaging. The camera is a little heavier than the diagonal and eyepiece. Could this be the cause?
How tight should the RA axis be? Mine spins evenly but I wouldn't say freely. The Dec is similar.
