Antonio, what would the astronomical coordinates align to in your view?
Would they be the coordinates of the stars themselves? Then they would have to align with the location of the viewer, on Earth, right? And a time to view them at those coordinates, or at least be found in relation to a fixed point of some kind that is viewable by all, or at least many.
Or, could it be data for computing the position of the Sun, Moon and planets relative to the fixed stars? That i could see, it has been done several times, the Toledan tables is an example, coordinates with Toledo as the viewing place.
The Alfonsine tables of 1252 were an update of the Toledan tables

Quire 13 i see as geographical and hydrological, with the nymphs standing for the human aspect of the geography, the societies that lived there. They are gigantic in relation to the waterbodies shown, you would be able to see them from space, if they were real.
As each place can be a set of coordinates on a map, or listed as directions and distances in a rutter, they can also have astronomical coordinates. When sailors set off to a far place, they aligned themselves with navigable stars. These could be what are on f68v1 and 2. There is a modern list of 58 navigable stars of which 19 are of first magnitude...these numbers dont fall too far from those in the above mentioned pages, the circles in the middle of some could denote first magnitude.

The stars kind of do come down to earth, or come up from it, in a visual sense, without the need of tubes et al, depending on the direction you look, from where, and when you look. So i could see some form of astronomical coordinates being involved, but we have to keep worķing on how that could have been achieved and what the meaning would be ascribed to said coordinates.
