The Ultimate Ball Head clamps are at a 45-degree angle and other Ball Heads they are horizontal. The angle of the ball clamps affects the range of motion.You can also rotate the Ultimate Ball-Head 180 degrees and then the range of motion is from forwards to straight up which is excellent for night sky photography.
