However, I have the standard Skywatcher rack & pinion focuser on my scope, and I'm wondering if the supplied fitting kit that comes with the Sharpsky will be sufficient to attach it to this focuser.

Any ideas?

Thanks,
In my experience it is best to have the motor coupled with the shaft of a 10:1 micro focuser rather than directly 1:1. Just for torque consideration and smoother tracking. Having said that it's a terrific little unit. A must have IMHO. The pic is when I had it fitted on my 90mm APO. Just make sure the motor shaft is inline with the coupler and focuser pin then make brackets to work your way back to a solid face of the scope.

PS: added similar setup on FSQ.
