My goodness, I can't imagine what a dull life must be like when contemporary imaging makes it all so easy.
What you fail to understand, Gerald, is that astronomers knew all about the motions of the inner planets long before you discovered "contemporary imaging". They did not actually need this "contemporary imaging" to fully understand what is going on. You
are just late to the party!
The original Sun-centred astronomers like Copernicus and Galileo had to framework their conclusion via a hypothesis as there was no means to view the central Sun at the centre of all planetary motions directly and a solar eclipse would have been of
little use in this respect. Now there are permanent eclipse conditions where we can see both to the left and right of the Sun and watch Venus and Mercury run their smaller and faster circuits back and forth (direct/retrograde motions) around our parent
star.
There is no hypothesis needed as the logic is that the motion of the Earth creates the annual change in the position of the stars from left (evening appearance) to right (morning appearance) of our parent star thereby setting the Sun up as a central and
stationary reference for the motions of Venus and Mercury-

Mercury has just transitioned to a dawn appearance as it moves between the Earth and the Sun so will be seen shortly.
There is a great love of the original astronomers who did not have the imaging tools available to distinguish the direct/retrograde motions of the slower-moving planets seen from a faster-moving Earth and the faster-moving inner planets seen from a
slower-moving Earth as different frameworks are needed-

The purpose of genuine innovators is to make themselves invisible so that only the perspectives themselves shine in the darkness. Trying to diminish the messenger is an offence against inspiration and that is never a good place to be. I don't mind the
silence because the good will eventually shine through and not even those who claim priority when it doesn't really matter. It is a Christian thing -
" And now, brother, listen to the conclusion. Above all the graces and all the gifts of the Holy Spirit which Christ grants to his friends, is the grace of overcoming oneself, and accepting willingly, out of love for Christ, all suffering, injury,
discomfort and contempt; for in all other gifts of God we cannot glory, seeing they proceed not from ourselves but from God " St Francis of Assisi
