Astronomical telescopes are used for observation

Our astronomical telescope can be widely used for astronomical observation, teaching aids, cultivating parent-child relationships, and exploring the mysteries of the universe.

A total lunar eclipse is a type of lunar eclipse that occurs when the moon, earth, and sun are in the same line and the entire moon fully enters the Earth's umbra. When a total lunar eclipse occurs, the sunlight reflected by the moon enters the Earth's atmosphere and scatters blue light in the opposite direction, making it appear red when observed on Earth.

The process of a total lunar eclipse can be divided into five stages: initial depletion, post eclipse, post eclipse, post eclipse, and post eclipse.

Initial loss: The moon has just touched the Earth's umbra, marking the beginning of the lunar eclipse.

Shiji: The western edge of the moon is inscribed with the western edge of the Earth's umbra, and the moon just fully enters the Earth's umbra.

Shi Shen: The center of the moon is closest to the center of the Earth's umbra.

Shengguang: The eastern edge of the Moon intersects with the eastern edge of the Earth's umbra, marking the end of the total eclipse phase.

Conjugation: The western edge of the moon is tangent to the eastern edge of the Earth's umbra, marking the end of the entire lunar eclipse process.
