OK one easier way to confirm that Airy disk isn't a "star". Speed of Moon movement vs stars was well known and is around 0.5'' per second, and Airy disk was 4-5

OK one easier way to confirm that Airy disk isn't a "star". Speed of Moon movement vs stars was well known and is around 0.5'' per second, and Airy disk was 4-5'' wide. So, when a star is occulted by Moon, it should have disappeared slowly as the Moon "slides" over it, during ~10 seconds. In fact, it disappears instantly, because Airy disk isn't a star...
