About this product
Model: hel_lightquest-hr_16x80_30144
Part Number: 30144
These high-end Helios LightQuest-HR observation binoculars combine top mechanical and optical design for outstanding performance!
They are fully waterproof (IPX7 standard, 0.5m depth for 30 minutes) and nitrogen-filled for clear, fog-free operation. They have individual eyepiece (IF) focusing and are designed for medium-to-long-range terrestrial and astronomical observations.
The body is constructed from magnesium alloy, making the binoculars surprisingly lightweight for an instrument of this size while maintaining a robust structure. The body is covered in tactile rubber armour.
Features include high-index BaK-4 prisms, a fully broadband multi-coated optical system, and shockproof caged prisms. The high-resolution optical system features high-transmission lens and prism coatings that allow a massive light throughput equal to or exceeding 90%. 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.
They are 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.

I have had the Helios LightQuest HR 16x80 binoculars for a few weeks now, and they continue to impress me. Build quality is great, while the weight is little more than the older (and also very good) Apollo 15x70s. The tethered lens caps are a clear improvement over the Apollo 15x70s too. Image quality is great, with stars remaining sharp over most of the field. Only at the very edge does some astigmatism show. No field curvature is noticeable. Eye relief for the 16x80 is generous, and I have no difficulties seeing the entire field of view with my glasses on. The three Messier cluster in Auriga show far more detail than in the Apollo 15x70s. On the moon, some chromatic aberation is visible, but it is not intrusive to me, and it is to be expected without apochromatic objectives.
The binoculars handle well, and I can readily use them without mount for short sessions, although the image is clearly more steady on a monopod or my p-mount.
In conclusion: great binoculars, real keepers
