Easily a high enough resolution to provide smooth tracking. Cant remember the actual figure, but EQ6's are significantly higher in their step size (and use microstepping as well) and no-one complains about seeing jumps in the eyepiece.....

I think the step size is quoted as .9deg (54 arc minutes not 9 arc secs).
In any case I would expect the drive to be similar to the NEQ6-pro and using micro stepping with a 300 tooth worm wheel it could use direct coupling to the worm to give sub arc second steps and smooth operation. However this information is not given directly in the promo.
