Sunday morning April 23rd the thin 26-day old waning crescent Moon will rise to right, west, from the inner planet Venus. The two will be about 6o apart and will easily fit within the field of view of 7×50 binoculars.
Sunday morning, April 16th the 19-day old waning gibbous Moon will rise near the planet Saturn. The two will be within the 7o field of view of 10×50 binoculars and will be easily seen over the eastern to southeastern horizon in the hours before the sun rises.

Thursday evening April 6th and Friday morning April 7th the waxing gibbous Moon will rise and then set with Regulus, the brightest star in Leo the Lion. During the course of the night the Moon will pass within about 1o-2o from Regulus.
Thursday evening April 6th, after sunset, look toward the west for a reddish appearing star. That is the planet Mars and about 2o to the east, left side, from Mars is Dwarf Planet Ceres, the closest of the dwarf planets. Not sure about Mars? Look for the Pleiades, an open star cluster with the brighter stars having a small dipper shape. Below the Pleiades is Mars.
In the early morning hours before the Sun rises the summer (northern hemisphere) Milky Way arches across the sky from the southern horizon toward the northern horizon. Over the southern horizon is the constellation Sagittarius the Archer and the direction toward the center of the Milky Way Galaxy. In this direction is the planet Saturn and within the field of view of binoculars are several nebula, some of which are visible to the naked eye.
Despite the use of optical aids like binoculars or telescopes we do not see the colors of these object that you may see in photographs. Regardless, this part of the sky is filled with many objects visible to the naked eye and certainly with binoculars. And assuming the local skies are relatively dark then viewing this area of the Milky Way will provide many viewing rewards.
Friday evening March 31st the 4-day old waxing crescent Moon will be about 4o from the reddish star Aldebaran in the open star cluster The Hyades. This open star cluster has a noticeable v-shape and from mythology the v-shape is the face of Taurus the Bull. Over the course of several hours as the Moon continues moving eastward along its orbit the Moon will pass across the v-shape and will be less than one-half degree from Aldebaran.
From my longitude this part of the sky will have set but observers in parts of north Africa, India, and that part of the world may be able to see an occultation of Aldebaran by the Moon. This animated graphic shows the Moon’s motion from 9 pm CDT 31 March to 5 am CDT 1 April (2 UT 1 April to 9 UT 1 April).
The point of the v-shape is the bull’s nose while the two stars at the open end, Aldebaran and Epsilon Taurus mark the bull’s eyes. To the right, west, from the Moon is another open star cluster The Pleiades.
The Moon reaches perigee for the second time, (minimum distance from Earth), this month on Thursday March 30th. At that time the Moon will more or less be at a distance of 28.5 Earth diameters (363,853 km or 226,088 miles) from the Earth.
Does our Moon actually go around the Earth as this graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*
On the day of the perigee Moon the 3-day old waxing crescent Moon is over the western horizon at sunset local time, above to the left from Mars, and Mars sets a few hours after the Sun sets.
