Description
The Bresser astronomical binoculars line has been expanded with the Spezial-Astro 15x70 (1551570) model, which meets all the basic requirements for astronomical instruments. The 70 mm objective lens collects enough light for observations of double stars, star clusters and planetary observations. Thanks to the 15x magnification and the possibility of mounting on a tripod, this model will be an ideal option for stationary landscape observations, observations of city landmarks, observations of bird migration or the movement of ships at sea. Despite the low cost, the binoculars have fully multi-coated illuminated optics, placed in a durable and lightweight housing. The classic arrangement of Porro prisms made of BAK4 optical glass ensures the transmission of a three-dimensional image evenly bright throughout the entire field of view. The optical layout allowed us to reduce the minimum focusing distance to 22 meters, which is a really good indicator for binoculars of this layout.
