The new LIGHTQUEST-HR observation binoculars are Helios' top end binoculars. Each model combines top-end features both in mechanical and optical design, with outstanding optical performance to match! These binoculars are designed for medium-to-long-range terrestrial and astronomical observations.

Lightquest's are fully waterproof to IPX7 standard (0.5m depth for 30 minutes) and are nitrogen filled for clear fog-free operation. Each ocular has individual eyepiece (IF) focusing. The body material is constructed from magnesium alloy making the binocular extremely lightweight for an instrument of this size, whilst maintaining a very robust structure. The body is covered in stylish protective rubber armouring.

Each model have high-index BaK-4 prisms and a fully broadband multi-coated optical system and their caged prisms offer a very good level of shock resistance. The precise optical system features high-transmission lens and prism coatings which have an extremely low level of reflectivity. This results in a light throughput equal to or exceeding 90% with images being delivered to the eye that 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 and fold-down rubber eyecups are provided for spectacle-wearers. Each model is supplied with captive objective lens caps, eyepiece rainguard, neoprene neck strap and heavy-duty tripod adaptor (attached to binocular in photo), in padded durable fabric carrying case.
