The Sky-Watcher 102/500 AZ-Go2 is a 102mm Achromatic Refractor Telescope that come with short focal length of 500mm. This noticeably shorter tube compared to other telescopes of the same class allows it to deliver a wider field of view with standard eyepieces. The compressed length of the telescope makes it convenient for it to be packed up and stored away while not in use or in transit. Images viewed through a refractor telescope have a classic quality that other telescope designs lack. Since a refractor does not use mirrors to view objects, you get a generally sharper image. Images are also displayed without the secondary mirror shadow, making it suitable for terrestrial viewing when used with a 45° erecting image diagonal provided.
