Mick, when I had some images like that is was DEC problems. If your polar alignment is good you can turn off DEC compensation altogether - there is not PEC on DEC. The other thing I found recently is not to balance in Dec too well, you want to keep the gears loaded and driven in one direction only (uphill). Try turning DEC correction off.
