This powerful Omegon 15x70 Nightstar binocular is the 'little brother' of the 20x80 model, and is lighter and more compact. Nevertheless, these 15x70's are perfect for wandering through the night sky. With an exit pupil of 4.7 mm, the view through the binoculars is very clear, making them also suitable for nature observation in twilight. All lens elements are multi-coated, which ensures an improved optical image. The binoculars offer an impressively bright image and a sharp field of view that is clear right up to the edge. The rubber eyecups fit precisely in the eye sockets to increase the comfort of the observer. Spectacle wearers are also catered for: the rubber eyecups can be folded down and with an eye relief of 18 mm, almost every spectacle wearer can see the entire field of view. The 70 mm aperture optics provide about twice as much light as binoculars with a 50 mm aperture. However, the size and weight are not significantly larger than those of binoculars with a smaller aperture.
