Yes..sort of..maybe. I tried that with my 40D but found I needed a bright star to do it. I was shooting 47 Tuc but could not focus on it in Live View. I ended up using Achernar which may have been too bright. I had some mirror shift issues when slewing from Achernar to the glob. If you use a newt or a refractor you would probably have better success.

I have yet to determine what the limiting magnitude of Live View is.
