Now and then I want to do a polar alignment with my LX600, and I use the automatic drift alignment method. 

 

As it is said in the manual, the telescope slews to a southern star and begin monitoring the stars’ drift.

 

My problem is that I have some city-light pollution in the south, so the stars are less easy to find there.

 

I would think that Starlock would pick one of the brighter stars in the area, but Starlock end up tracking on a rather dim star, even if there are brighter and more suitable stars next to it.

 

Sometimes it works fine, but it often ends with a “star lost” message and I have to start over.

 

Is there a way to choose the star myself?

Starlock would opt for a star not too bright and not too dim, too bright it would not get a good notice of drift.   You might hold off 30 minutes to an hour after dark before attempting that type of auto drift.  You can shut starlock off and do a manual drift test though.  Another possibility is to put a light shield extension on the end of the starlock to help cut down on the off axis light which might be messing with calibration.
