From a rotation you would not be able to get anything but great circles
around the rotational axis (Stars tracing constant latitude w.r.t. that
axis).
Agreed.
The ellipses are very small and arise from the parallaxes arising from
the TRANSLATIONAL motion of Earth in its orbit around the Sun.
Am I right in saying that the major axis of these ellipses are equal in length? This is what I refer to as 'aberration'.
