I know the routines your are talking about ... i am attempting to remove the error of the human hand from the equation and make it a mechanical adjustment run via a computer to a much higher resolution than woulld be possible by hand.
The worm gear i am looking at coupled with the step size of the motor should give a resolution of about .5 arc second per step in the alt axis and 0.3 arc seconds per step in the az axis.
I could simply work out the error correction (say 7.5 arc minutes in Alt) needed and tell the stepper motors to move the 900 steps to get the alt axis aligned.
