Description
The Bresser line of astronomical binoculars has been replenished with a high-quality model with improved optical and operational characteristics, the Spezial-Astro SF 15x70 WP, which stands on par with the latest models for astronomy in its class. In accordance with specialized astro-binoculars, this model has separate focusing on the skin of the eyepieces, which ensures maximum image sharpness at any astronomical level in all ranges diopter correction. It is also important to note that in order to prevent fogging, the binoculars are filled not with traditional nitrogen, but with argon, which can always be added to inert gases, which does not react for normal minds with other chemicals elements, saving the troubling hour of their cob power. The eyepieces are folded into five lenses, grouped in three groups, and ensure a high level of image correction and achieve a high angle of view. The extra-spherical illumination of all optical surfaces and the BAK4 prism is transmitted evenly across the entire image field. The 70mm lens picks up enough light to capture high-altitude stars, bright spots and planetary sights. Regardless of its main importance, this device can be successfully used for stationary landscape monitoring, monitoring of bird monuments, monitoring the migration of birds or the movement of ships at sea at a view from one a kilometer or more.
The aluminum body of the binoculars has high rigidity and low flexibility. The classical arrangement of Porro prisms creates a more plastic image with a sense of triviality. The optical layout made it possible to change the minimum focusing distance to 10 meters, which is a really good indicator for binoculars of a similar design. Binocular accessories are also highly rated. The lens caps are attached with straps to the body, which makes them easy to wear out. Our neoprene belt is wide enough so as not to put pressure on your neck and shoulders when transporting the binoculars. A case with fittings that look like fastex, customized for this model, so the binoculars fit perfectly in it and don’t sit in the middle.
