Thank you. That reveals more about where you're coming from than
myriad
questions on alt.horology were able to.

I had restricted the astronomical material to the emergence of the 24
hour clock system and the isolation of axial rotation to 24 hours/360
degrees as being of interest to horologists in an era which assigns a
garbage value of 23 hours 56 min 04 sec to axial rotation in a
calendrically driven justification.Your posting requires a response in
an area which isolates orbital motion from axial rotation,and while not
immediately relevent to horologists,it demonstrates the benefits of
keeping axial and orbital motions seperate for their seperate purposes.
Both the Ptolemaic and Copernican astronomers used the astrological
plotted motions of the planets against the stellar background even
though their conclusions differ as to what those motions represented by
isolating orbital motion of the observed planets.

Using the invaluable and actual time lapse footage of Jupiter and
Saturn above it is easy to see how the Ptolemaic could have seen
periodic looping motions of the planets as seen from a stationary
Earth.
Using the same footage,it is easy to see how Copernicus reasoned that
it is an orbitally moving Earth that generates the effect just as a
car,moving in an inner lane on a traffic roundabout would pass slower
cars moving in an outer lane.
Both Ptolemaic and Copernican astronomies used the common plotted data
and drew their conclusions of the motions of planets,as seen directly
from Earth,I repeated as seen directly from Earth.This perspective is
absent from Newtonian quasi-geocentricity insofar as he mixes epicycles
with astrological retrogrades and does not acknowledge that planetary
motions can be resolved by direct observations (unlike Ptolemaic and
Copernican astronomers) -
"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 goes on to retain the stellar background in his quasi-geocentric
format* leading to this Dystopian era which praises his awful reasoning
as being a human accomplishment.In conclusion,Ptolemaic and Copernican
astronomy part company with astrological plotting in terms of assigning
the arrangement and motion of the solar system planets in isolation
hence Newtonian conceptions based on John Flamsteed's sidereal format
is by far inferior to the uselfullnes of the original astrological
plotting of planetary motions using the stellar background.
* "PHÆNOMENON IV.
That the fixed stars being at rest, the periodic times of the five
primary planets, and (whether of the sun about the earth, or) of the
earth about the sun, are in the sesquiplicate proportion of their mean
distances from the sun."
