You still see the same star size image, regardless, Paul.
LiveView works wonderfully well, even when zoomed in. The tiniest movement of the focuser shows the star image change.
Couple the Bahtinov Mask along with the Bahnitov Grabber software (interactively shows you how far out of focus you are and suggests racking in or out until star is in focus), and it is wonderful for DSLR work.
