the scale did blow my mind as well, I just did an extememly rough calc with the picture/ map

distance to the back of the ring is approx 441km, the ionisphere is 300km high giving the angle to the back of the circle to be around 34deg

with the front being 144km - giving an approx angle of 64deg high up

which kinda of fits the picture
