Thanks John.
I bought the mount used but it had never been opened or set up.? It came from company seven and I was told they test each mount.? The motors are not tucked.??
I was just outside with it and maybe it just doesn't play well with the asiair.? I generally have to go back to cwd, shut everything down, restart the mount, restart the air....it gets tedious.? I have avoided Nina because of windows.??
Ok. So it just flipped.? RA guiding went from around 2 before the flip to 0.5 now. And my stars are round.? It always improves after the flip with the scope on the east side.??
Tom,

It is possible that you have an RA worm gear which is rougher on one side of the threads than the other, which would explain the change in guide performance after a flip. But that should not have changed with the new extensions and would have been there all along. You can buy a new high precision brass worm from Losmandy which may give you better results. If you do go to that length of replacing it, you might want to consider a rebuild and change out the worm bearings, and the thrust bearings as well. Some time, elbow grease and determination are required here :).
