These classic porro-prism binoculars provide maximum image brightness: The beam of light that leaves the eyepiece (the so-called ‘exit pupil’), is seven millimetres in diameter – about the same size as your dilated pupils at night. This means that no light is wasted, and lets you see faint objects such as nebulae or comets more clearly, as well as animals at twilight. The multi-coated lenses ensure high light transmittance and prevent distracting reflections.
The Cometron’s wide field of view lets you observe large areas of sky to easily locate your target object and then keep it in view. Whether you are looking for an astronomical object in the sky or a terrestrial object on the ground when nature-watching, the wide field of view is always an advantage. The generous eye relief also ensures comfortable viewing and makes these binoculars suitable for spectacle wearers too – no matter whether you wear glasses normally or wear sunglasses for nature-watching on a sunny day.
