I am looking at the other thread of the astrophotographer and there isn't the slightest hint of describing the moon's orbital motion in terms of a Sun centered structure nor the positions of the three celestial bodies in relation to each other. In this case I marvel at the reflected light of the Earth on the moon's surface as the fully illuminated face of the Earth stands directly against the fully dark face of the moon at the moment of the eclipse -

There is some joy in being able to reason why the same face of the moon can be seen on the eclipse much like it is seen each full moon with the difference between reflected light of the Earth for the former and direct radiation from the Sun for the latter.
