Abstract: A telescope, including a microdisplay, a beam combiner, a dichroitic beam splitter, and an image sensor. The beam combiner receives light from an objective lens and the microdisplay, and mixes same. The dichroitic beam splitter allows at least part of invisible light and a small part of visible light having a predetermined wavelength to enter a second optical path leading to the image sensor. The image sensor obtains a detection image representing an optical image formed by the objective lens and an electronic image displayed on the microdisplay. Also disclosed are an electronic eyepiece and an eyepiece adapter for the telescope. The detection image representing the optical image and the electronic image can be obtained.

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: Disclosed are an astronomical telescope stand, an auxiliary calibration method for the astronomical telescope and an astronomical telescope system. The astronomical telescope includes at least two rotating shafts perpendicular to each other, each rotating shaft is provided with an encoder; an electronic camera shooting in the same direction as the telescope to be mounted; a display screen; a processor that connects with the encoder, the electronic camera and the display screen; the processor includes an image information parsing module, an electronic image generation module and a coordinate correction module. The telescope is mounted on the stand, and the electronic camera shoots the same image as the image observed by the telescope. The image information parsing module solves the image to obtain the center coordinate and the field size of the image. The electronic image generation module generates the simulated image according to the center coordinate and the field size.

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.
