Thanks everybody.
Mickoid, somebody in a recent thread said they used a Vixen Polarie Meter,
so I got one, and for now sat it on top of the tracker and used it to set the altitude. The compass on it is not that good, being difficult to get repeatability
of readings, so the azimuth is probably not as good as I'd like. The best I
could get for perfectly round stars at 30mm was 90 secs. More experimenting
necessary. I'll have to get a separate compass.
Cam,I was only experimenting, and the camera's battery expired, otherwise there would have been many more subs.
Nice to hear from you Dunk.
