Observing the moon


Dear all, today I wish to clarify a puzzling matter that has had many skywatchers (including myself) scratching their heads; namely, the question of our Moon’s seemingly bizarre ‘behaviour’ and apparently fluctuating tilts / orientations as viewed from Earth. To be sure, spatial perspective is a quite challenging subject matter – especially when it comes to astronomical observations, what with all its angular variables (diverse earthly locations / observational frames of reference, oscillating seasonal tilts, latitudes & longitudes of our moons and planets, etc). This present exercise will also provide another opportunity to demonstrate the usefulness of the Tychosium 3D simulator and what I like to call its “explanatory power”.
