Achromatic refractor featuring an objective lens diameter of 70 mm and a focal length of 900 mm.
Capable of gathering 98 times more light than the naked eye at night, the lens telescope is installed on a equatorial mount. The lightweight configuration makes it easy to transport to different locations, for instance, moving away from artificial lights that impair nighttime sky viewing. Delivers an image that is both bright and high in contrast.
