Royal Observatory Porro Binocular 7x50mm

Product Description

Coated optics dramatically increase light transmission bringing celestial objects into bright, sharp focus, for brighter images with increased contrast and resolution and the large exit pupil provides maximum light during night-time and low-light viewing sessions.

These binoculars are designed and intended for use by those 14 years of age and older and make the perfect introduction to binocular sky watching, night sky observation and astronomy.

Also suitable for birdwatching, trainspotting and other hobbies. Great portability means these binoculars are easy to carry in a rucksack or in the car.

Caution: viewing the sun may cause permanent eye damage. Do not view the sun with your binoculars or with the naked eye.
