Vixen 2.1x42 Super Wide Constellation Binocular # 19172

A 2.1x42 binocular? No that's not a typo. These ingenious little optics are based on Galileo's original telescope design to give you up to an incredible 25o field of view at an ultra-low magnification. You can take in entire constellations like Cygnus and Sagittarius and cruise along the rich star fields of the Milky Way to see star clusters, diffuse nebulae, star clouds, and inky-black archipelagos of dark nebulae set against the background stars. Early users of these new binoculars have said it's like observing the night sky with "super vision".

• Large 42mm lenses with 5 multi-coated elements increase brightness of stars by more than 4x and let you see thousands more stars than with the unaided eye
• High-quality Japanese-made optics and mechanics include matte-black interior and baffling to reduce stray reflections and maximize contrast
• Weighs just 410g for ease of use and comfort during long observing sessions
• Eyepieces with 8.4mm of eye relief focus individually for optimum binocular viewing
• Includes eyecups and case

These binoculars are based on the design of a Galilean telescope, which has different characteristics than the more common 'Keplerian' telescope. This means the true field of view depends on the proximity of your eye to the eyepiece lens. So if you wear eyeglasses while observing, you may see a smaller field of view. At the eye relief of 8.4mm, for example, the true field of view is about 12°. The optics also give an erect image without prisms, which makes for the lowest possible optical loss and even brighter images.
