#30158 (DO-1550) Binoculars DELTA SKY GUIDE 15x70 The binoculars feature 70 mm objective lenses and a fixed 15x magnification, making them ideal for stargazing at night. The housing is sealed and filled with nitrogen to prevent internal fogging. They are equipped with Porro prisms made of BaK4 glass and treated with fully multi-coated (FMC) optics, which reduce glare and reflections. Chromatic aberration is also minimized, providing a 4.4° field of view at 15x magnification. The body is rubber-armored, ensuring a secure grip, preventing slipping, and offering extra protection by absorbing minor impacts. The focus can be adjusted individually for each eyepiece.
