Head up, Stargazers! The wax crescent moon appears close enough in the hours after sunset on July 28th on the left Mars shoulder -so that both of them fit easily into the view of a 10×50 deficit duty.
The crescent moon will be visible on July 28th at sunset 20 degrees above the western horizon, with Mars as the light light point appearing about four degrees. Both the Mars and the stars of the nearby constellations are more pronounced when the shine of the setting sun makes room for the coming night.
Around this time, the moon and Mars will be close enough to fit into the field of vision of a 10×50 long -distance glass, which will help to recognize the dark oval of the mare rod (the crisisemeer), which marks the northeastern region of the surface of the moon. The 460 mile width basalt level (740 kilometers) was formed by lava flows that flooded the impact pool when an asteroid saver of 25 miles collided with the moon about 4 billion years ago. (Mare Crisium was also the landing site of Firefly Aerospace’s robot Blue Ghost SpaceCraft, which landed there in March.)
The Mars now appears as a bright red star for the exposure eye and by binoculars, while a telescope with an aperture of 4 inches (10 centimeters) or more enables the resolution of surface features on the red planet. A Schmidt-Cassegrain with an aperture of 20 cm (about 8 inches), according to telescopic manufacturer Celestron, offers an even clearer view of the polar ice caps and dark puzzling regions that mark the neighboring world of the earth.
As always, the greatest care must be accepted when observing objects near the ascending or exceeding sun. You can ensure that our parent star is safe under the horizon by checking the sunset for your area scheme via a website like Timeanddate.com or in-sky.org.

Both the Mars and the WachsCrescent moon will go under about two hours after the sun on July 28th. Therefore, make a good view of the western horizon to maximize your viewing time.
