I observed the same effect when the seeing was bad and I was trying to capture "Bird's stike" on Jupiter. I found that it (the central bar) did wander slightly but it was easy to judge the center. I suppose its a good way to test the seeing, but without the mask I found it very difficult to judge best focus.
