The crescent Moon is an important part of some religious observances today, and was for many cultures of antiquity. The theoretical limit of a visible crescent is approximately 12 - 14 hours under perfect conditions, before or after a New Moon. A waxing crescent is seen at dusk in the western sky, while a waning crescent is seen at dawn in the eastern sky - how close can you come?
Warning: While binoculars can help to spot a slim crescent Moon, it is very dangerous to use them near the Sun. Binoculars are not recommended if the Sun is above the horizon.
