DESCRIPTION The telescope was invented by Johns Hopkins University and released on July 1. The purpose of this study is to achieve maximum magnification at the smallest effective aperture while ensuring the luminous flux and resolution angle of the telescope. This telescope is the first attempt to use nano-etching technology, nano-array technology, mesoporous assembly technology, thin-film mosaic technology, and nano-optical materials to make the flatness error of the lens reach 10nm. The luminous flux reaches 30 times that of ordinary telescopes with the same diameter. The resolution angle is 47 times that of ordinary telescopes with the same diameter. The maximum magnification reached 300 times. This is the first monocular to achieve this magnification and clarity on such a small scale. FEATURES   If there are no terrain obstacles, you can easily observe people or things 6 miles away by using it. The built-in night vision function allows you to use it normally at night.
