3t and 3u. The viewer now appears to be in a slight bowl. Looking horizontally the viewer does not see the sky but rather the surface. Even looking at an angle slightly up, the viewer would be observing the surface, no matter which azimuthal direction is observed. This is because of the photon orbits that are trapped.
Some photon orbits leave the neutron star and fall back, never reaching infinity.
If the viewer looks along these paths, the viewer will be looking slightly up and still seeing an image of the surface. As before, the apparent line dividing land and sky still marks the apparent position of the photon sphere. Also, as before, when orbiting at the photon sphere, the sky Einstein rings are all seen above the apparent photon sphere position. The many surface Einstein rings and complete images of the stellar surface are contained just below the photon sphere, although they together occupy only a thin sliver below the photon sphere. In the last sequence, the viewer pans around to see the whole neutron star surface.
