About this product
Part Number: 30141
The new high-end Helios LightQuest-HR observation binoculars combine top features in mechanical and optical design, with outstanding performance to match!
They are fully waterproof (IPX7 standard, 1m depth for 30 minutes) and nitrogen filled for clear fog-free operation, with individual eyepiece (IF) focusing and designed for medium-to-long-range terrestrial and astronomical observations.
The body material is constructed from magnesium alloy making the binocular extremely lightweight, whilst maintaining a very robust structure. The body is covered in stylish hard textured leatherette.
Features high-index BaK-4 prisms and a fully broadband multi-coated optical system and shockproof caged prisms. The high-resolution optical system features high-transmission lens and prism coatings allowing a massive light throughput equal to or exceeding 90%. The lens coatings have an extremely low level of reflectivity, ensuring the maximum amount of precious light is provided at the eyepiece. Images delivered are vibrant, very flat edge-to-edge and virtually distortion free.
The advanced innovative eyepiece design (8 elements in 5 groups) features oversized eye lens elements for comfortable viewing and provides a highly corrected image. Fold-down rubber eyecups are provided for spectacle-wearers.
Supplied with objective lens caps, eyepiece rainguard, neoprene neck strap and heavy-duty tripod adaptor, in durable padded fabric carrying case.

The design and build quality of these binoculars is excellent and preliminary casual daylight observations revealed a sharp and high contrast image. The fold-down ‘rubber’ eyecups allowed me to see the full field of view whilst wearing spectacles, however, when they are turned down, the ‘rainguard’ will not fit. The clear dioptre markings on the barrels of each eyepiece made pre-setting to a known focus easy and when focused to infinity they aligned accurately with the zero mark. The prisms are cage mounted and all optical surfaces, including the prisms, appear to be well anti-reflection coated. At night-time these binoculars really come into their own. Stellar images proved to be very sharp on axis and over much of the field, being only a little less so near the edge. Poor seeing has prevented me testing performance on extended astronomical object at this stage. In my view the Helios LightQuest HR 10x50 is a excellent astronomical binocular either hand-held or tripod mounted and at £269 it’s a bargain.
