How to get stars in focus?

[Jarmo]

I don't have live view so what i do is use high ISO and wide aperture so exposure time is short and adjust the focus so i'm close then take a shot. Look at the photo zoomed in. If needed i refocus a bit and keep checking until i have good focus. Then set ISO and other settings to what i want and take the shot...

When I didn't have live view on my previous camera I just used the view finder and got a far away lamppost in focus.
