Anyone find a good driver for the LX-850? Which of the Meade is best?

Use INDI LX200 GPS driver.

Hi,

I have a problem whit the slew and track functions of the KStars whit this telescope, I chose for example Jupiter click on slew and the telescope does not reach the planet, and the red dot on KStars neither, (the red dot looks like pointing acording to the telescope position) for a long distance like 30 degrees, is like the problem is some missing configuration, latitude or something, but the observation site looks correct, what could be?

Was the mount already aligned before you connected? If yes, then check time and location. If problem keeps persisting, enable INDI Mount logging and attach the log.
