Too far away horizontally speaking, because of the shallow angle between observer and star, there's too much atmolayer to look through.
So, because of the "atmolayer" (your version of our Atmosphere) I can see, in my southern hemisphere, stars to the south, east, west and UP, but not the northern stars?
the same for the north hemisphere, they can see stars to the north, east, west and up, but not the southern stars?
Very weird your atmolayer....
