The trouble with those who call themselves astronomers today is that they are not serious or dedicated people. Their silly ideas based on astronomical language are careless and indulgent so nothing productive or creative ever gets done.
In the matter of observations, interpretations and conclusions, they lack the necessary judgments to realise what is being demonstrated, even with the benefits of modern imaging and graphics.
Kepler's diagram of the motions of Mars and Earth is a case in point as the diagram is neither geocentric nor geostatic as the theorists imagine but, gauged against the background constellations, represents both the motion of the Earth and Mars-

"Copernicus, by attributing a single annual motion to the earth, entirely rids the planets of these extremely intricate coils, leading the individual planets into their respective orbits, quite bare and very nearly circular. In the period of time shown
in the diagram, Mars traverses one and the same orbit as many times as the 'garlands' you see looped towards the centre, with one extra, making nine times, while at the same time, the Earth repeats its circle sixteen times " Kepler Astronomia Nova 1609
Like all his followers, Newton thinks the diagram is geocentric hence his relative/space and motion so if the Sun is plonked into the centre of the diagram then the direct/retrograde loops disappear hence-
"For to the Earth planetary motions appear sometimes direct, sometimes stationary, nay, and sometimes retrograde. But from the Sun they are always seen direct,..." Newton
How many times has this vandalism been presented to a readership who has no interest whatsoever in interpreting observations but rather misusing them for self-aggrandising and financially lucrative purposes?
Nowadays there are two different ways to explain direct/retrograde motions. Copernicus and Kepler had the fixed stellar background to work with in the absence of satellites that can now look directly towards the inner solar system hence the satisfactory
explanation for the slower-moving planets-

When faced with something momentous like the ability to account for the observed motions of Venus and Mercury without the need for a hypothesis, no serious researchers exist.
