Yeah I've noticed that. At times I've turned the autoguide off and the dec has just hummed along nicely on its own

Not last night though. So maybe its a combination of both flexure and polar alignment. If its fine again tonight I'll have another go. I'll spend more time than usual and make sure the polar alignment is running smoothly for at least 5 minutes. That will take one variable out of the equation. I might even have a read of the Losmandy manual and see how the backlash compensator works on the mount.
I'll see what I can do to strenthen the guiderings. If the new ones are no better when they get there I'll send them back and maybe get a set of Losmandy guiderings. I've heard they're pretty good

What I'd really like is to get a "Side-by_Side" mount head so the guidescope is not attached to the imaging scope. Might have to work on that. couldn't be too difficult to make.
