Akira, it is a proyection. The show has a lot circles within circles, planets, rotations and son on. Theere is a circular proyection screen. There was banding on the proyected images unless slower than 1/40th of a second shutter speed. In here, the image was fixed in photoshop from the original one: nikon z6, 70-200 2.8e @70mm and f2.8, 1/160, iso 1600, silent shutter.
