Help on basic design question about stepper motor control

[De Messemaeker Johan <Johan.DeMessemaeker@advalvas.be>]

Hi,

I'm planning on motorize a telescope with a couple of stepper-motors
controlled through a parallel port. My only question here is: do I have to
use a realtime control for this ?

Normally, I would say no but I think it would be wise to use a rt-control
because i'd like to implement an auto-guiding mechanisme.
