It should also be noted that the Moon sets before the Sun in the light brown-shaded area covering most of the globe with the exception of most of the Americas. Telescopic sightings of the crescent moon with small, conventional amateur-sized telescopes as well as sightings with the naked eye are also extremely unlikely on a global basis.
