The knob removes parallax. Relative movement between the cross hair and target when u move your head back and forth while looking through the scope. No parallax, no relative movement and you get a clear picture. It does the same thing as an adjustable objective. Evidently to move the adjustment from the front to the side adds more glass to the side focus or side parallax. More weight and not as bright.
