Friday evening December 14th the first quarter Moon, Mars, and Neptune will all be within the field of view of binoculars.
Monday December 10th the 3.5-day old waxing crescent Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
Saturday evening December 8th the 1.6-day young waxing crescent Moon will be in conjunction with the outer ringed planet Saturn. The two will be within about 3o from each other. Joining the Moon and Saturn is the Dwarf Planet Pluto, and further to the east are the planets Uranus, Neptune, and Mars.
Within the field of view of 7×50 binoculars, in addition to the Moon and Saturn, are several Messier Objects, M-22, M-25, and M-26. These may be a challenge to see given that they are low over the western horizon and by the time the sky is darker they will have set or are just about to set.
Wednesday morning December 5th the very thin 28-day old waning crescent Moon will be within 4-5o from the innermost planet Mercury. Venus shines very brightly above or west from the Moon. About an hour after the Moon and Mercury have risen the outer planet Jupiter will rise above the eastern horizon.
Sunday evening November 11th the 3.5-day old waxing crescent Moon will be within 2-3o east (left) of the outer ringed planet Saturn. The two should look good through a wide-field eyepiece at ow magnification, and through binoculars.

In addition to the Moon moving along in its orbit the Earth is also moving eastward along its orbit around the Sun. As the Earth revolves the sky shifts toward the west gradually moving the stars closer to the western horizon. Even the planets gradually shift toward the western horizon and out of sight.
Tuesday November 6th the 28-day old very thin waning crescent Moon will be near the inner planet Venus, the star Spica in Virgo the Harvest Maiden, and Dwarf Planet Ceres as they all rise an hour or so before sunrise. The waning crescent Moon has an apparent magnitude of -8.55 compared with Venus apparent magnitude of -4.32, Spica with an apparent magnitude of 0.96, and Dwarf Planet Ceres with an apparent magnitude of 8.18.
