Thanks Ray
A part of me wants to go and turf half of my subs as they're the less round of the lot. The star trailing is along the azimuth axis, ie, following the same direction as when I am polar aligning the azimuth. I assume this is differential flexure and not misalignment. T-Point tells me that I am usually ~30" off in PA which shouldn't be causing enough drift in 15 minutes when guiding. I do get some pretty large RA spikes though :/
