focusing

Hi to everyone, I am using a canon Xti with a 8" SCT. This camera does not have 'live focus'.
Would it be possible to somehow hook the camera to my laptop and focus it that way?
As always, I thankyou, bob

Yes. That's exactly what I do. And this is what I use:

In addition, you're gonna need a shutter interface cable from Shoestring Astronomy, but, believe me, once you get used to focusing and controlling the camera from a laptop you will never go back.
