Description
The Bresser line of astronomical binoculars has been replenished with the inexpensive Spezial-Astro 25x70 model, which provides all the basic functions to astronomical devices. The 70mm lens picks up enough light to capture high-altitude stars, bright spots and planetary sights. Due to the great 25-fold increase in the ability to install on a tripod, this model will be an ideal option for stationary landscape monitoring, monitoring of public monuments, monitoring the migration of birds and the movement of ships at sea. the distance is two kilometers or more.
Regardless of their low quality, the binoculars feature highly coated optics and are housed in a durable, lightweight aluminum body. The classic arrangement of Porro prisms from the BAK4 optical glass ensures the transmission of a trivial image that is uniformly bright across the entire field of view. 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.
