About 15 minutes later, 3rd magnitude stars became visible, and so forth until about 90 minutes after sunset, the faintest 6th magnitude stars were visible. We now rate each successive magnitude as 2.5 times fainter than the magnitude before. For example, Polaris is 2nd magnitude, and about 2.5 times fainter than 1st magnitude Deneb. You can find the magnitude scale in your sky map legends. He found many fuzzy objects that immediately appeared to be a comet, but which did not move against the star field, as comets orbiting the sun.
Cometary movement becomes obvious in just a few hours.
