Hmmm - no comments?
The NEQ/HEQ mounts have 1.8 degree stepper motors and a gear ratio of 1:705 this gives 9.19 arc sec/ step.
The guide rates in Synscan go down to x0.125 Sidereal rate (=15 arc sec/ sec / 8 = 1.8 arc sec/ sec
By my reckoning too achieve a guide correction of 0.1 arc sec, the motor would have to be micro-stepped at 9.19/0.1 = 1/92 steps to give the required correction.
Based on the lowest Synscan guide rate it would require a pulse of 1/18 sec....
