Description
technical field [0001] The application belongs to the field of electronic equipment, and in particular relates to a device for measuring the seeing degree of an observatory site. Background technique [0002] Among the various indicators of the observatory site, seeing is one of the most important indicators. For large telescopes that do not use adaptive optics, the angular diameter of the star image is determined by seeing. A 4m telescope placed on a site with a seeing degree of 2 arcseconds, compared with a 2m telescope placed on a site with a seeing degree of 1 arcsecond, has the same limiting magnitude, and the resolution of the latter is better high. Seeing is the brightness flickering, shape destruction, and position change of astrological images caused by the earth's atmosphere. Seeing is the total result of atmospheric influences at different altitudes. Generally, the atmosphere below 30m in height is called the ground layer, which can be sampled and observed wit...
