Default Time lapse footage

When possible,it is always much better to put observations in proper
context with time lapse footage and the following spectacular footage
of Uranus qualifies as something unique -

It is possible to see how axial rotation and rotational orientation
(axial tilt) is seperate from the motion of the rings with respect to
the central Sun.In short,the polar axis of Uranus does not tilt
through 360 degrees as it orbits the same central Sun that we
orbit,what is occuring is that a location will orbitally swing through
360 degrees like a crank turning around a central shaft -

The Earth has an orbital component that turns through 360 degrees to
the central Sun just as a location on Uranus does,while that component
is seen in terms of variable axial inclination,it is hoped that there
are just enough genuine astronomers who can intepret the time lapse
footage of Uranus correctly and identify the same component for the
Earth which generates seasonal variations in daylight/darkness and the
variations in the natural noon cycles.

It is not every day a person gets a chance to celebrate a new way to
look at the Earth's motions and its effects but that is a personal
choice allied with a bit of astronomical talent.It is also enjoyable
and a worthy way to celebrate the power of modern imaging.Perhaps when
people get tired of the unobservable junk dumped into the celestial
arena and start to look at what can be experienced (the seasons/
astronomical motions) then this great discipline will returnb to its
former glory.
