Well, that's why I usually say, "It leans more toward astronomy than astrology..." since astronomy as we know it doesn't exist and the distinction between astrology and astronomy was significantly less than it is now.
There are some that lean toward astrology and kabbalah, often with magical associations, star seals, and associated incantations, and those that lean more toward describing the shapes of constellations which, in some areas, is as close as they got to astronomy in those days.
I suppose in modern terms it might lean more toward astrology, but in medieval terms, it's pretty "scientific" compared to manuscripts that describe hordes of angels and devils specifically associated with stars, with various means of invoking them and carving them onto talismans.
