Computerized telescopes are similar to conventional telescopes, except the computerized version is controlled and guided by a computer, while a conventional one is moved by a person. Having computerized controls means computerized telescopes are afforded many advantages that can help both new and seasoned astronomers and stargazers. These telescopes have no chance of human error when looking at specific coordinates, because the user just types in navigational numbers and the telescope will turn in the correct direction and angle. Most computer telescopes also have saved coordinates so users can see planets and nebulae without needing to aimlessly search for them, or question whether he or she is looking at the right star. There also are recording and touring features that allow users to record space phenomena or save certain coordinates.
With computerized telescopes, the computer controls all movements, so everything is precise down to the exact degree. Conventional telescopes force users to check direction, adjust the axis to move the telescope and measure degrees to ensure the user is looking in the right area. Computerized versions do all this work; the user just types in the navigational information and the telescope aims itself.
Planets, nebulae and other celestial bodies follow a designated track that has been calculated by astronomers with high levels of accuracy. This allows most computerized telescopes to come with a program or function that allows users to quickly find these bodies without having to search for minutes or hours. The user types in the date and what celestial body he or she wants to see, and the telescope will aim itself. Many stars and celestial features look similar, so this also helps astronomers differentiate the bodies without having to question their own judgment.
While most of the space that computerized telescopes can see is already known, there may be an odd celestial body or occurrence that is outside the norm. Most computer telescopes are able to record these instances onto the computer’s hard drive. This means the user will have proof of anything strange, whereas conventional telescope users would be unable to record images or video.
Star and planet touring also is possible with computerized telescopes. Either from a pre-made path or a path the user makes manually, the telescope can tour from one celestial body to another. This helps the user search through various bodies with accuracy and speed, and allows him or her to see only celestial bodies of interest.
