In outer space, three pinhole cameras are pointed in X, Y and Z directions (these are in uniform linear motion, the same as Sun). Cameras are pretty large. In the camera, on the inner wall, on the opposite side of the pinhole, disks rotate once and receiving position of star lights are recorded.

Recorded position of star lights on three disks will not be true circle. These may indicate motion of the pinhole cameras relative to aether.
