An all-time multifunctional telescope device that can be used for solar active region observation and night astronomical observation

Abstract

An all-day multifunctional telescope device capable of being both used for solar active region observation and night astronomical observation comprises an optical telescope system, a lightweight cellular main lens and temperature control system, a thermovision field diaphragm and temperature control system, a thermovision field diaphragm adjusting structure, an achromatic imaging system, a light filter, a rotating rack and a data processing and control system. According to the all-day multifunctional telescope device capable of being both used for solar active region observation and night astronomical observation, under the condition that cost and system complexity are not obviously increased, the effective observation time of the telescope device is changed to achieve daytime and night continuous observation from only daytime or night observation, the effective observation time is effectively prolonged, the observation efficiency is improved, important reference is provided for development of telescopes, in particular to development of large-diameter telescopes, and the innovativeness and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of solar telescope devices and nighttime astronomical observation telescopes, in particular to an all-time multifunctional telescope device used for solar active region observation and nighttime astronomical observations. Background technique [0002] Aperture size is one of the most important performance evaluation indicators for any telescope device. Qualitatively speaking, the larger the aperture of the telescope, the stronger its ability to observe details, that is, the higher spatial resolution; at the same time, the larger the aperture of the telescope device, the stronger its light-collecting ability. The light capacity is increased by 3 to 4 times, and the higher light-gathering capacity enables the telescope to observe solar active regions or nighttime astronomy with higher time resolution and higher spectral resolution. But on the other hand, with the continuous increase of telescope aperture, its...

Problems solved by technology

[0005] According to the above background description, it can be seen that the large-aperture solar telescope equipment can only observe solar activities during the day, and will be in a "rest" state after entering the night, thus causing a waste of resources for high-resolution imaging equipment

The telescopes used for nighttime astronomical observations can only be used for nighttime astronomical observations because they are not designed to take into account the characteristics of solar observations.

For back-end instruments and equipment, the two telescopes cannot be used together

In order to achieve continuous observation of solar active regions and nighttime astronomy, at least two sets of telescope systems and their corresponding terminal equipment need to be developed, resulting in a great waste of human resources, financial resources, and use efficiency.

Moreover, with the continuous increase of the telescope diameter, large-aperture telescope equipment can only conduct high-resolution observations of the sun's surface active area during the day or night astronomy at night, and it is impossible to use the same large-aperture telescope equipment to achieve high-resolution observations of the sun's surface active area during the daytime. High-resolution observation, high-resolution observation of night astronomy at night, resulting in a great waste of human resources, financial resources, use efficiency, etc. Observation time and low efficiency restrict the further development of telescopes
