When the moon is exactly half illuminated (upper or lower moon) when viewed on the earth, the earth-moon-sun is at right angles, the angular distance between the sun and the moon in the sky can be measured, and then the earth-sun distance can be calculated through the earth-moon distance. Specifically, as shown in fig. 12, a small hole is drilled in the middle of two hollow tubes, and the two hollow tubes are strung together by a thin nail for measuring the included angle between the sun and the moon. The moon can be aimed through the hollow tube, but when the other hollow tube aims at the sun, eyes can not be used for watching, burn is prevented, the shadow of the hollow tube can be adjusted against a piece of paper, and the shadow is aligned when the shadow is at least one point. And measuring the included angle, and obtaining the distance between the sun and the earth by using a cosine formula.
SE＝ME/cos(δ)
The benefits of the above embodiment are that students can feel longer distances such as daily click and click through meditation by taking the perceived distances as the starting points, such as the familiar distances from home and school, shanghai to Hangzhou and the like, and can extend to the earth diameter, the earth month distance, the earth day distance and the path and diameter of the earth revolution orbit half-year time by a triangulation method, and the space sense is expanded step by step to gradually build universe and world view, so that the space sense is built, and the space sense is formed to be a graceful and credible sense of looking down the way and looking up the sky.
As a further improvement of the embodiment, in one embodiment, the virtual astronomical platform can be arranged at the roof of a school, and can also be arranged in a scenic spot for waiting birds, viewing stars at night and birds at daytime and paying for the virtual astronomical platform.
According to longitude, latitude and altitude, the position of the sun on the celestial sphere is calculated according to time, and according to the field of view of the second ocular lens, the protection range of the equatorial telescope is dynamically updated to prevent the sun from imaging on the second ocular lens and burning the second ocular lens. Because the second eyepiece is far larger in field of view than the first eyepiece, the sun does not enter the second eyepiece, and naturally does not enter the first eyepiece. This function is particularly important when used for sightseeing birds on sunny days.
