Once your shot is in focus, you have found your infinity focal point, just change your focus button to manual focus. You can also mark your exact focus point.
Second Method: Using live view at night. Set your focus ring as close to the ∞ (infinity) symbol as possible. Turn on live view and point your camera at the brightest star or object in the sky. Zoom all the way in. Adjust your focus ring until the light from star looks as small as possible.
