You can also focus on something 50-100 yards away in good light. When you get focus on that point, tape your lens down, so you can't move it. That should be the infinity point, and as others have said here it is not necessarily the farthest point you can focus on the lens. Once you have that point, you should be able to point the camera on what you want to shoot, say the milky way, and it should be good.
