Some people do it that way, using a "clock" drive. I found it easy to track actively with the inexpensive redrock sensor. The clock drive accuracy would have to be periodically checked anyway with some sort of active monitor.

It's not a clock drive; apparently it is tracking the light source. That is why you see it backtrack sometimes -- I guess it sees more light at the edge of a cloud sometimes.
