Philippe Posth, you wrote:
"I think that celestial globes are printed "as seen from the outside" because it is easier for graduations."

But that is false.

You added:
"Note that the same is true for the StarFinder 2102-D. These instruments are not intended to represent the sky as it appears to us, but to allow the user to determine the height and azimuth of a celestial body or to identify a celestial body whose height and azimuth have been measured, for a given place and time."

And this is why we can't have nice things. You're expressing the Fallacy of Perfect Engineering. The device was designed in a certain way, and that certain way must be respected as the "genius of the ancestors". But the 2102-D StarFinder is a piece of junk. It is poorly designed. Navigators are kidnapped by it --they engage in a type of self-brainwashing. They decide that they must learn its point of view, and they must adopt and respect its point of view. And when their souls are crushed, they become its biggest fans. Yet at the end of the day, the thing itself has not changed: the 2102-D StarFinder is a piece of junk.
