The starry sky in April is particularly bright. Mars, the most anticipated astronomical spectacle of this month, will be staged on April 17.

The lunar eclipse of Mars took place on the night of April 17 in Beijing. The lunar phase of the day is Omei, and the brightness of Mars is about 1.5. It will cover the dark side of the moon and the bright side of the moon. (address:click

Most areas of Hainan Island, South China Sea Islands, Southwest Yunnan, Xigaze, Tibet and other places can see the astronomical phenomena, while other areas of China can see the Mars moon with closer angular distance. At the time of Mars lunar syncopation, the position of Mars in the center of the earth is just 7 minutes north of the moon. At night on April 17, Mars was about one degree away from the moon. Then it kept approaching and fell to the horizon at about 22:50 p.m.

When the astronomical phenomena occur, the brightness of Mars is fair, and the phase of the moon is relatively appropriate. Therefore, you can observe it through binoculars or small telescopes. You can also connect the camera with an astronomical telescope and take a direct focus shot to record the moment.

However, due to the fact that Mars is far away from the earth, its apparent diameter is small, and its elevation angle is low, it is difficult to see the surface details, so high-power photography is not recommended.
