8C10.55 - View of the Galactic Center from a Spiral Arm
Reposition the arm so that one end is at the center of the rotating platform. Mount the globe stand at the center of rotation and mount the Nerf ball at camera height. The camera represents our position at the edge of one of the spiral arms with the Nerf ball representing the galactic center. The view as the arm is rotated should show some parallax and a great deal of background movement in relation to the galactic center.
