About this image

This is the Mk 2 version (for Mk1 see below). Using a flat ring as the base has improved the stability of the polar-axis holders, which have been redesigned. Each mini-Earth is fully rotatable and the axial inclination is reasonably accurate given the scale. I'm fairly satisfied with this version. I have uploaded a clearer image.

On reflection, the stand for the Sun is rather obtrusive. A Mk 3 version looks a possibility ...!
