3. Observers in the Home Frame will conclude that the clocks in an Other Frame will be out of synchronization, even if the observers in the Other Frame have carefully synchronized clocks using the Einstein prescription.

The two-lens astronomical telescope constructed for the experiment produces an inverted image of the object. To convert the astronomical telescope to a terrestrial telescope, mount an inverting lens in the system. Determine the position for an inverting lens that will not change the magnification of the telescope
