Abstract: An IT-based astronomical telescope system comprises a rotatable lens barrel having an eyepiece installed thereon; a detection device for detecting a current orientation of the lens barrel; and an image generator comprising a micro display provided in the lens barrel. The image generator is used to obtain a picture and display the picture on the micro display. The IT-based astronomical telescope system is configured to work in a virtual reality mode, in which: the image generator is turned on, and based on the current orientation of the lens barrel detected by the detection device, obtains a picture corresponding to an optical image of stars supposed to be imaged by the telescope system with the current orientation of the lens barrel; and the micro display displays the picture, which is presented through the eyepiece.

Abstract: An augmented reality telescope comprises an optical image acquisition module, an electronic image acquisition module, an imaging module communicating optically to the optical image acquisition module and the electronic image acquisition module, and an image observation module open optically to the imaging module. The optical image acquisition module is arranged for the acquisition of object images by means of optical acquisition, and the electronic image acquisition module is arranged for the acquisition of object images in the form of electronic imaging. Since the imaging module is simultaneously open optically to the optical image acquisition module and the electronic image acquisition module, a mixed display of the optical image and the electronic image is realized.

Abstract: A polar axis calibration system (100) comprises: a polar scope (10), a polar axis calibration control device (20) and a display device (30). The polar scope comprises an optical lens (11) and an image sensor (12) for collecting constellation images (IM); the polar axis calibration control device receives the constellation images from the polar scope and determines the position (P1) of the rotation center of the polar axis and the celestial pole position (P2), the position of the rotation center of the polar axis means the position of the rotation center (R0) of the polar axis (510) of the equatorial instrument in the plane of the constellation image, and the celestial pole position means the position of the celestial pole in the plane of the constellation image; and the display device is coupled to the polar axis calibration control device and used to display the constellation image, the celestial pole position and the position of the rotation center of the polar axis.
