Guide stars and guiding

Thanks for the heads-up photos Robert, very cool.

A layman's question for you. Did the Keck telescope use a separate optical system when guiding on a star (the old way) or did it use one found in the FOV from the main lens?

And what is the lowest visual Mag. of a star have you pointed at for guiding and how do you locate that star, with the aide of optics or on screen enhancement?
