I have an LX-90. It will certainly continue to track an object, until you tell it to do otherwise. I have walked away for an hour and returned to find Jupiter still reasonably well centred in a low power eyepiece.

If you set it up in Alt-Az mode, I have found that how long it will keep an object centred for depends on a couple of things:
a. how level your tripod is
b. how well did you centre the two alignment stars
c. how recently you have performed a "Train Drive", nb. this is not Periodic Error Training. Much easier to do - best done on a distant object in daylight

Accurate polar-alignment on the wedge/tripod is much more difficult. The whole structure can "bounce" significantly - it's just not rigid enough for my liking.

Cheers
