"Where these (16x80) binoculars really excelled was on open clusters and extended deep-sky objects such as galaxies and bright nebulae. The Pleiades leapt out at us, its collection of hot blue-white stars blazing like diamonds under a spotlight"  BBC SKY AT NIGHT MAGAZINE

High quality filled observation binoculars, with individual eyepiece (IF) focusing, designed for medium-to-long-range terrestrial and astronomical observations. They are fully waterproof (IPX7 standard, 1m depth for 30 minutes) and nitrogen filled for clear fog-free operation. Shockproof design incorporating a robust but lightweight magnesium alloy body construction, covered in stylish protective black rubber armouring. Features BaK-4 prisms and a fully broadband multi-coated optical system. The optical system features high-transmission lens and prism coatings allowing 85% light transmission. Eyepiece design features oversized elements, generous eye-relief and fold-down rubber eyecups for spectacle-wearers. Features integral tripod mounting column and central stabilising bar. Supplied in soft storage/carrying case with padded neck strap, eyepiece rainguard and objective lens caps.
