The stars in the sky

Loly and José are soldiers from different branches; but they are good friends, since they met in a unit where they worked together. Although Loly is a connoisseur of cosmography, she has interesting opinions and serendipitous discoveries.
José, despite not fully understanding what her friend does measuring at night, gladly helps her with her notes, following her dictation of the vertical angles of this or that star, with curiosity and desire to learn.
The two almost always meet at their leisure, but depending on whether the night is clear, they head to a location far from the city, set up the theodolite, and begin observations. Yes, José also sees curious details about the movements of the stars that Loly explains to him how they occur.
