What distinguishes you from all astronomers,and even in antiquity they made the distinction,is that they set aside the idea of 'overhead' or 'above' when dealing with conceptual matters as 'below' has no real meaning and this is why you appear as homocentrists as you presently lack the feel for anything outside your rotating celestial sphere or the Ra/Dec culture. This from Plutarch -
"But yet, it is proved unreasonable, and repugnant to facts, to suppose the ?above? of the world to be a whole, but the ?below? an incorporeal and indefinite limit: whereas that course is consistent with reason, to say, as we do, that the space is large and possessed of width, and is defined by the ?above? and the ?below? of locality." Plutarch
We have many American patriots here in this forum,they should have no problem standing before their students and explaining that as the Earth travels in a circle around the central Sun,the background stars closest to the plane of the Earth's motion disappear behind the Sun for a period and Sirius just happens to coincide close to Independence day,the information here being that putting Sirius in stellar circumpolar motion as you are doing with rise/set times,obscures a rich astronomical history,everything from planetary dynamics to timekeeping.
Without the slightest fear of objection you try to diminish the great astronomical heritages which you yourselves can't use and even though there is a great satisfaction in knowing that when Sirius re-appears at the orbital point in August as the Earth swings around and brings the star out of the glare of the Sun,we will move in its direction and then 10 months later watch as the Earth's orbital motion at the light of the central Sun envelops the star once more.
Any star crosses a person's meridian 1461 times in 1461 days and the Egyptians used the orbital emergence of Sirius from behind the Sun as a gauge for the balance between days and years,or in modern terms,rotations and orbital circuits -
I see that wishful thinking junk of relativity and a star at an eclipse in 1919 but the real astronomical value is acquiring a feel for the appearance of Sirius in terms of the orbital motion of the Earth.I have yet to see this happen where a person can escape the rotating celestial sphere of Ra/Dec and look out at the stars with a different perspective and certainly Sirius provides a good incentive.
