I've found I get the best focus by finding a not-so-bright star (sorry can't give you Mag figure), then the star 'disappears' from the live view window either side of the focus sweet spot. Seems to work the best for me - if I focus and lock on say Sirius, I find that the brightness of the star blurs that sweet spot a bit.
