Hi Martin,

Yep, EOS Utility Remote Shooting/Live View is indispensible.

The way I've focused in the past is to monitor the chromatic aberration on the star in Live View. With each nudge you give the lens, you'll see colour change from red to blue. Once you're in the middle, you know that you're pretty much in focus. It only takes a couple of minutes to do it. Of course, you could us a Bahtinov Mask and the Bahtinov Grabber software to take all the guesswork out of it. I don't have a mask small enough for a lens, but, I know Chris (Omaroo) does and his works beautifully.

And, yep, just disable IS whilst shooting; if you're running on batteries, you'll drain them pretty quickly with IS enabled!
