Thanks Glen and Bill, i thought that if you found 3 points of reference it would accurately find the target and stay on the target. Because when it goes off target if i redirect back to target it finds it again. being an IT guy that doesn't make sense, but you wisdom sounds correct i will try to get an accurate polar alignment and see if that helps much appreciated.
So you guys are basically saying it will find the target ok. But will drift off if not polar aligned.
much appreciated David
