Thanks for additional comments.
The drive actually uses a friction clutch that is tightened to drive the steel roller which rives the horseshoe ring. So no belts involved in the RA drive.
I actually sent the drive back to Losmandy soon after I got the scope because the crystal they had installed caused a rocking back and forth motion to the RA drive.
I actually now think that JMI have not been able to get the steel roller to be 100% accurate in size to allow the RA drive to operate accurately at such a high focal length.
So another solution would be to have a slightly smaller RA roller that turns the RA horseshoe ring slightly slower - BUT, that might cause it to go too slow as well.
Last night I did image at a different rate setting and added some weight on the East side of the scope and this has definitely made a difference and eliminated 50% of the issue. As the scope is not permanently mounted and is wheeled in and out to a pre dedicated pad, this also contributes.
I think the best solution is when Firecapture allows me to guide and capture at the same time - I think even at 1 second corrections, I will play with this, and should get quite close, although I would like this to be shorter perhaps when a Firecapture update occurs.
Thanks again for suggestions.
