Thanks for the ideas Greg,
I've decided to attack flexure from a few angles.
Adjust and tighten the focusers on the ST80 and the 127ED.
Install a 12mm thick dovetail between the imaging and guide scope.
Change the EQ6 head to an ADM Losmandy-style dovetail foot.
Last but not least, rebuild the EQ6 and replace those crappy bearings. On inspection, the worm bearings have flat spots and would play havoc with tracking and guiding.
Cheers,
Rob
