Thanks Dennis and Brendan
Yes, it has worked previously and is still working near the celestial equator. It only starts to play up the further south I go.
It will not calibrate. After 50 or so steps trying to calibrate in RA it will stop and tell me that there is not enough movement in the star to calibrate in RA.
The scope is balanced as close to perfect as can be. A 30gram sinker will start it moving in RA.
A good 10 minutes exposure without any Dec. guiding can be taken with the Canon 400D.
I normally have guiding in Dec. turned of.
RA is a different story.
Have increased/decreased agressiveness without any luck. Have also increased the time interval from 2.5sec to 10sec between checken for drift whilst PHD is guiding.

PS: I meant Leon from Ballarat, noyt Leo, who, if I remember rightly ahd that problem a while back
