Favorite binoculars for astronomical observation lovers. Hundreds of enthusiasts associate their first moments with binoculars under a starry sky with binoculars SkyGuide 15x70. Its affordable price and sensational optics have become legendary. SkyGuide enlarges the image 15x, and thanks to lenses with a diameter of 70 mm it achieves a very good star range.
The lenses are coated with multilayer FMC anti-reflection coatings on all optical elements. The correct correction of chromatic aberration and a comfortable, large, comfortable field of view of 4.4◦ at 15x magnification were also taken care of. Large prisms made of glass BaK4 are a standard in binoculars from the SkyGuide series.
Apart from good quality optics, the mechanical solutions used deserve attention. The entire body of the binoculars, including the tubes in which the lenses are embedded, is made of metal and rubber-coated. This advantageous solution is used extremely rarely in this price class of binoculars. The sharpness is adjusted individually for each eyepiece - there are no mechanical problems with clearance on the eyepiece bridge. This ensures that the binoculars will perform well for years to come.
An elegant case for storing and transporting the device is supplied with the binoculars.
