Embodiment Construction

[0011] refer to figure 1 and figure 2 , the specific embodiment adopts the following technical solutions: it comprises projection display 1, projection obscura 2, target sight 3, astronomical telescope 4, longitude and latitude adjuster 5, tripod 6; projection display 1 is arranged on the front end of projection obscura 2, and projection The rear end of the camera obscura 2 is connected with the astronomical telescope 4, and the front end of the astronomical telescope 4 is provided with a target sight 3, the projection camera obscura 2 is arranged on the tripod 6, and the latitude and longitude adjuster 5 is arranged below the projection display 1.

[0012] During the operation of this specific embodiment, the light of the sun (celestial body) is focused by the 4 objective lenses of the astronomical telescope, and then the prism is used to turn the angle, and the positive mirror filters the light, so that the light spot is projected in the projection obscura 2, and then irrad...

Abstract

The invention discloses a refraction-projection type solar activity display device and relates to the field of astronomical observation equipment. A projection display (1) is arranged at the front end of a projection camera obscura (2), the rear end of the projection camera obscura (2) is connected with an astronomical telescope (4), a target aiming lens (3) is arranged at the front end of the astronomical telescope (4), the projection camera obscura (2) is arranged on a tripod (6), and a longitude and latitude adjuster (5) is arranged under the projection display (1). The refraction-projection type solar activity display device is applicable to astronomical observation clubs of primary and secondary schools as well as astronomical observatories of universities and colleges, rapid in looking for targets in astronomical observation, accurate in focusing, convenient to record, easy to take photos, capable of being recorded by multiple people with one-step imaging, high in observation efficiency and ideal in effect of observing and recording sun spots.

Description

[0001] Technical field: [0002] The invention relates to the field of astronomical observation equipment, in particular to a refraction projection type solar activity display device. Background technique: [0003] After the astronomical observation team used the refracting telescope to observe and record the amount and the moon at night, they needed to set up again when observing sunspots in the daytime, because when observing and recording sunspots, they needed to add filters or "black mirrors" with high concentration, and the concentration was too high Then you can’t see the sunspots clearly, and the concentration becomes smaller and it is particularly dazzling. Sometimes you can only set up a projection board to let more students observe together. [0004] The projection board is designed to be in the shadow of direct sunlight, and the image is very blurred. When it is rainy, you can only rush to record in the gaps in the clouds, and the effect is not ideal. Inven...
