Default Focus on RA/Dec modeling concluded

In the end it comes down to the most simple question imaginable and in the 21st century there are no excuses for getting it wrong or ignoring the actual principles of timekeeping in tandem with the Lat/Long system .

Computer modelling is a tool which will be held back by the clockwork solar system of the theorists (RA/Dec) however this period has now come to an end. In straightforward thinking, the new software program will subtract any rotational element which is wrapped up in the 24 hour weekday and its anchor in the natural noon cycle where the natural variations arise from an orbital surface rotation and therefore orbital motion.

It means that observers can enjoy the transition of celestial objects from either the left to right or right to left of the stationary Sun due to their intrinsic orbital motions or because of the Earth's own orbital motion. No longer the 'fixed stars' of RA/Dec but the fixed and stationary central star of our parent Sun.

That image was taken a day ago as Venus travels in behind the Sun and will reappear as an evening appearance as it moves from right to left of the Sun while the Earth will catch up with Jupiter hence that planet will not make the transition shortly but when it does it will transition from left to right of the Sun. The principle here is that everything is referenced to the distant Sun and not the local horizon and especially not using a celestial sphere framework.
