comment Calculate telescope orientation based on RA, DEC and Lat/Long
What do you need to calculate? DEC and RA are the celestial coordinates, so they are "where" the telescope is pointing at.

Could you please provide a link to that table? Maybe it is easier to interpret it directly than from your explanation.

comment Why planet's orbit is not perpendicular or random ?
Typical deflection time does not mean that all deflections take place at that moment. There are deflections way before that. Think in typical height for men in your country. Are there men higher than that? And shorter?

comment Motion of the sun as observed from mercury
The combination of two movements, one "horizontal" with forward and backward and one "vertical" caused by the inclination of the Axis, the same one we experience on Earth where Sun is higher in sky in summer and lower in winter.

Elliptical galaxies are dwarf galaxies, sort of giant globullar clusters, so they have had the same processes as globullar clusters, including huge amounts of interactions and ejections. Each star, indeed, keeps its own Angular Momentum, and the system as a whole (elliptical galaxy plus ejected stars) does as well, but the galaxy not counting the ejections, which is the observable body, does not.

The intercation among stars on galaxies is very tiny. Globular clusters have a density of 10^5 to 10^6 stars in a very small sphere (on the magnitude of 1pc, almost never reaching 10pc), while galaxies have a density of 10^11 or 10^12 stars in an enormous disk (on the magnitude of 10^4 or 10^5pc)
