Hi ngchunter nice work liked the video, does software like Stellarium not do that if you use the time date to look at a past date?
Stellarium generally uses VSOP87, not Newcomb's tables. Stellarium's end result is quite accurate, there's nothing wrong with it, but I don't
know if they let you specify the atmospheric pressure/temperature to increase the accuracy of the atmospheric refraction calculations. I know Cartes
du Ciel does have those settings available, but I haven't seen them on Stellarium.
The point of this was more to resurrect Newcomb's old data. It may have been inspired by a desire to prove wrong the claim that NASA and others are
lying and that astronomy programs are "being altered to covering up changes to the solar system" so that everything only looks like it's moving
normally, but it has uses beyond that. For most purposes it's more than accurate enough, and I rather enjoy dusting off unused books containing
historical data like this which used to form the basis of all astronomical almanacs. It's a bit like how some space enthusiasts spend their time
restoring an old unused telescope or spaceflight computer. Neither one will perform better than a modern equivalent, and it's much easier to get and
use a modern version, but the joy is in the learning process while doing the restoration. In the end there's also an intangible joy that comes from
seeing the old data working once again, and the results can be used by others as well.
