The unique range of motion and design of this head makes it perfectly suited to sit atop a star tracker for night sky photography and offer a dramatically increased range of motion for composition. This ultra-light head is durable, rugged and built to support crazy heavy loads. Mine lives next to my Move Shoot Move Nomad Star Tracker.
Here's what Acratech has to say about it.
The difference between the Ultimate Ball-Head and other Ball=Heads is the angle of the clamps that hold the ball. 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.
All Acratech Ball-Heads are designed to be lightweight and rugged for the active outdoor photographer. The open structure lets moisture, dirt and debris fall through instead of being trapped inside a socket.
