After using the calculator that my good friend Sethtriggs provided me, (and testing it with various examples), I think that the Milky Way would be about 20% of the size of the Sanyahona night sky. Considering that the sky looks like a dome, where objects get larger as they get closer to the horizon, I think the vision would still be very spectacular. So I have to shrink the relative size of the galaxy a little with respect to the mountainous horizon.
