High-end mechanical and optical qualities are combined with exceptional performance in the new Helios LightQuest HR 16x70 Observation Astronomy Binoculars 30143.
Helios LIGHTQUEST-HR observation binoculars have individual eyepiece (IF) focusing, are fully waterproof (IPX7 standard, 1m depth for 30 minutes), nitrogen filled for clear fog-free operation, and are made for medium to long-range terrestrial and astronomical investigations.
The body of the Helios LightQuest HR binocular is made of a magnesium alloy, making it incredibly light for a device of this size while still maintaining a very sturdy structure. Elegant firm textured leatherette covers the body.
This includes shockproof caged prisms, high-index BaK-4 prisms, a completely broadband multi-coated optical system, and more in the new LightQuest HR range. 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 8 elements/5 groups eyepiece design has extra-large eye lens components for comfortable viewing. For those who wear glasses, rubber eye cups that fold down are available.
Delivered in a sturdy padded fabric carrying box together with objective lens caps, eyepiece rain guards, neoprene neck straps, and a heavy-duty tripod adapter (seen attached to the binocular in the photo).
