The brand-new, top-of-the-line Helios LightQuest HR 20x100 Observation Astronomy Binoculars 30146 offer cutting-edge mechanical and optical design, as well as exceptional performance.
Specifically made for medium to long-range terrestrial and astronomical investigations, Helios LIGHTQUEST-HR are fully waterproof (IPX7 standard, 0.5m depth for 30 minutes), nitrogen filled for clear fog-free operation, and equipped with individual eyepiece (IF) focusing.
The body of the Helios LightQuest HR 20x100 Observation Binoculars is made of a magnesium alloy, which makes the binocular incredibly light for a device of this size while still keeping a very sturdy structure. The body is encased in fashionable rubber armour for protection.
High-index BaK-4 prisms and an entirely multi-coated optical system are hallmarks of the LightQuest HR. The level of shock resistance offered by caged prisms is excellent. High-transmission lens and prism coatings in the high-resolution optical system enable a significant light throughput of 90% or more. The incredibly low level of reflection of the lens coatings ensures that the eyepiece receives the maximum amount of priceless light. Delivered images are vivid, nearly distortion-free, and highly flat from edge to edge.
The cutting-edge, ground-breaking eyepiece design, which has eight elements in five groups, includes extra-large eye lens components for comfortable viewing and offers a finely corrected image. For those who wear glasses, rubber eye cups that fold down are available.
LightQuest HR has a central stabilising bar and an adjustable integrated tripod mounting column.
Supplied with a foam-lined durable carrying/storage container together with captive objective lens covers and eyepiece rain guard.
