Celestron UpClose G2 binoculars 8x40
Binoculars with a fixed magnification of 8x and a lens diameter of 40 mm.
The manufacturer used a Porro prism system - in which the objective lenses are not coaxial with the eyepiece lenses. Such a solution resulted in a fairly wide field of view of the binoculars - 143 m at a distance of 1000 m. Focus adjustment is carried out using the central knob, which is located between the binoculars' tubes .
The optical system of the binoculars is protected by a lightweight, handy rubber-coated housing, which absorbs accidental knocks and falls from small heights. The prisms used in the binoculars, are made of BK7 type optical glass .
The binoculars use MultiCoated technology - all air-glass boundaries are coated with anti-reflective coatings, thus minimizing unwanted reflections and losses of light passing through the optics.
Included with the binoculars are: a carrying case, a cloth for cleaning the optics, lens covers.
