I'm not sure of the point, I'm new to all this. I'm guessing there is not always a suitable guide-star, or that guiding doesn't solve all of the problems?
Does guiding get rid of concerns about PE and tracking errors in the mount?
Does a guided EQ6 work as well as a guided Titan if both are well inside their weight tolerances?
Those aren't rhetorical questions, I actually am confused about the whole mount issue

I am aware of those closed-loop systems, but they must be extremely expensive (encoder must be free of PE and backlash, which is not possible to achieve (at reasonable price) with up-gearing)- so I don't think they will ever be available for average user.
And what's the point? Guiding works well (not my own experience yet, though).
