Star observation method based on error angle self-adaptive adjustment and astronomical telescope

Abstract

The invention discloses a star observation method based on error angle adaptive adjustment and an astronomical telescope, and the method comprises the steps: querying the right ascension and declination information of a target star according to a star database; obtaining a first pitch angle and a first horizontal angle of the target star according to the query result and the current geographic position and time of the star observation device; ccording to the pre-stored error angle, eliminating an error of the first pitch angle / the first horizontal angle to obtain a second pitch angle / a secondhorizontal angle, wherein the error angle is obtained according to a third pitch angle and a third horizontal angle of the selected reference star body and a fourth pitch angle and a fourth horizontalangle of the star body shot by the equipment at the angle; and adjusting the star observation device to a second pitch angle and a second horizontal angle, and shooting an image. Error calibration does not need to be carried out after the telescope is started, self-adaptive adjustment is carried out according to the pre-calculated error angle, and the angle after error elimination is automatically adjusted for observation.

Description

technical field [0001] The invention relates to the field of astronomical telescopes, in particular to a star observation method and an astronomical telescope based on error angle adaptive adjustment. Background technique [0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. The refraction of the light through the lens or the reflection of the light by the concave mirror make it enter the small hole and converge into an image, and then pass through a magnifying eyepiece to be seen. [0003] The telescope equipment needs to adjust the angle of the telescope lens before searching for stars, so that the target star to be searched appears in the lens. In the prior art, after the telescope is turned on, error correction needs to be performed in advance, and then the equatorial mount and a series of angle sensors such as gyroscopes need to be used for detection and tracking during the star search process.

Problems solved by technology

In the prior art, after the telescope is turned on, error correction needs to be performed in advance, and then the equatorial mount and a series of angle sensors such as gyroscopes need to be used for detection and tracking during the star search process. However, the equatorial mount is heavy and expensive, and cannot Guaranteed no offline when tracking stars

[0004] In the existing technology, the telescope needs to be calibrated every time it is turned on, which is time-consuming and laborious, and the operator needs to have a certain level of calibration

[0005] There is a lack of adaptive adjustment technology for telescope error angles in the prior art
