Achromatic refractor with an objective lens diameter of 70 mm and a focal length of 900 mm.
This refractor telescope gathers 98x more light than the human eye at night. It is mounted on an alt-azimuth mount, and the whole setup is light enough to be easily moved to other locations, for example away from artificial light sources, which have an adverse effect on night sky observation. The viewed image is bright and high-contrast.
