That's why you can see so many southern stars at Midwinter's.
This is assuming that the line extends in both directions from the center of the Earth
And I think the amount of the southern celestial sphere visible from a given north latitude is the same every night of the year... though the sun being closest to the local nadir would probably make the sky darker. Is this what you were getting at?
