Hi Chris,
yes, it will be exactly like that.
Bartels scope.exe supports focuser with stepper motor, and I have my own little program for this purpose ( I posted it here on the forum last year I think).
The limitation is, focus should be moved only with help of computer.. but it is not a real problem.
I will have pretty good resolution, 0.05 um/step. Of course, internal gearbox of the motor is not that precise (motor is CZ2801, Taiwan), but it will still be precise enough (my mirror is F5.6, so there will be some margin for error).
