Dandong introduces the most advanced astronomical instruments in China

Introduction: In 2004, Dandong Science and Technology Museum was named the provincial science education base and became the only astronomical science education base in the province. With the passage of time, the astronomical facilities in the museum are gradually aging and it is difficult to meet the needs of observation and popular science education. To this end, the financial department of Dandong City won a special fund of 450,000 yuan at the beginning of this year for the transformation of equipment for science education bases.

In the vast space stars, the swirling galaxy slowly approached, and it was almost in close contact with people; Pegasus, Lyra, and other celestial bodies showed a three-dimensional eruption slowly passing by... At the afternoon of the 9th, Yongchang Primary School students had the honor of It became the first small audience to open up the transformation project of science and technology museum astronomy science education base, and the 3D celestial phenomenon demonstrated by digital planetarium lively surprised the children.

In 2004, Dandong Science and Technology Museum was named the provincial science education base and became the only astronomical science education base in the province. With the passage of time, the astronomical facilities in the museum are gradually aging and it is difficult to meet the needs of observation and popular science education. To this end, the financial department of Dandong City won a special fund of 450,000 yuan at the beginning of this year for the transformation of equipment for science education bases.

In April this year, the transformation work kicked off. Today, the original projection planetarium has been replaced with a digital planetarium, which can both play and demonstrate various 3D celestial phenomena and can also display astronomical science films. In particular, the demonstration of the sky is more three-dimensional and visualized, allowing observers to reach space. The original self-made telescope was replaced by an international standard astronomical high-definition telescope. In addition to the multiple increase, the observation object is farther and clearer, the diameter becomes larger, and the observation field is wider. "High-definition telescope with GPS positioning automatic finder function, is the most advanced science telescope in the country. As long as the input data, you can automatically track the celestial goals, observation is particularly convenient." Xu Hongguang said.

In addition, the original astronomical dome was replaced by an astronomical dome with astronomical industry standards. It is a built-in super hemisphere astronomy dome made of sheet metal and has a smooth overall surface. The dome moves smoothly and can rotate 360°. Astronomers observe the sky here and it will be a pleasure. In addition to updating astronomical instruments, the Science and Technology Museum has also transformed and expanded the astronomical science knowledge exhibition halls, so that the equipment of the city's popular science education base has been fully updated, and it has taken the lead in the province and the northeast region.
