Thankyou all for your contributions, all welcome. My confusion was
started by the fact that the error shown at the end of each iteration
of a star alignment is described in the Synscan manual as "Polar
Alignment Error". It would appear that that is not what it actually is.
Eden, my HEQ5 generally carries around 10.5kg, and you're right, I
balance it carefully with a little weight acting against the drive.
Well. I'll try out some of the suggestions and see how I go.
