How is the total lunar eclipse formed?

Using mobile phones or cameras and other photographic equipment, find a place with a wide field of vision to shoot the eclipse, which can form a picture.

If you want to shoot the stunning "quasi-red moon", first of all, it is recommended to use a SLR or a micro-monocular camera with a telephoto lens to get close-ups of various periods of the eclipse. Secondly, you can use the medium focal length to shoot, or you can use the wide-angle lens to shoot a "sequence image" showing the eclipse process. In the case of a small astronomical telescope, it is also a good choice to connect the camera body or mobile phone camera to the eyepiece of the telescope through a fixture or adapter ring for shooting. In addition, at present, major mobile phones can easily capture the solar eclipse, and a single photo is taken in automatic mode or night view mode. It is recommended to shoot recorded video or delayed video with a medium focal length (usually 3X or 5X).

Eclipse, also known as eclipse, is an astronomical phenomenon that when the moon moves into the shadow of the earth (the shadow is divided into umbra and penumbra), part or all of the sunlight can't be directly illuminated by the sunlight, so that observers on the earth can't see the ordinary moon phase. When the eclipse occurs, the sun, the earth and the moon are exactly or almost on the same straight line, so the eclipse must occur on the night of the full moon (the fifteenth, sixteenth or seventeenth lunar month).
