Information technology based astronomical telescope system

An IT-based astronomical telescope system, comprising:

• 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, wherein the image generator is used to obtain a picture and display the picture on the micro display,
• wherein, 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 which is corresponding to an optical image of stars supposed to be imaged by the IT-based astronomical telescope system with the current orientation of the lens barrel;
• and the micro display displays the picture, which is presented through the eyepiece of the IT-based astronomical telescope system with the current orientation of the lens barrel.
