About this product

Model:  hel_lightquest-hr_20x100_30146
Part Number:  30146

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, 0.5m 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 for an instrument of this size, whilst maintaining a very robust structure. The body is covered in stylish protective rubber armouring.

Features high-index BaK-4 prisms and a fully broadband multi-coated optical system. Caged prisms offer a very good level of shock resistance. 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.

Features adjustable integral tripod mounting column with central stabilising bar.

Supplied with captive objective lens caps and eyepiece rainguard in foam-lined hard storage/carrying case.

Helios LightQuest-HR 25 x 100mm Binos
Tuesday, 8 December 2020  | 

I was in a bit of a dilemma - I had already ordered the 80mm version of these binoculars when by chance a FLO customer returned a set of the 25x100s (being too large/heavy) - Alex at FLO was brilliant, he allowed me to cancel my initial order and purchase the larger versions. There are not many reviews of these binoculars, here is one: http://binocularsky.com/reviews/LightQuest_25x100.pdf - and it is very accurate to what I have experienced over the last few nights of observing. I already own two telescopes, but I was after a quick alternative to setting up a telescope, especially living here in Ireland where the the odds of cloud or rain ruining observation time under clear skies is certainly stacked against you.

The views from these binoculars is incredible, yes they are heavy and you certainly need a strong and steady tripod along with a heavy duty mount (especially to prevent backward mount movement when viewing objects 70 degrees or more). Star clusters are shown in all their glory, colour rendition is really accurate with different variations of stars being displayed correctly. Jupiter is glowing disc and its larger moons are apparent, Saturn's rings are also distinguishable. In relation to the various nebulae you can certainly identify these quite clearly. Last night (7/12/20) Orion's M42 almost filled the viewable frame of these binoculars - showing clear bright stars and a bluish glow of the surrounding nebula.

What would be advantageous if spending a decent amount of time observing with these binoculars is some form of dew shield - the objectives are quite exposed. Given that these are such good observational binoculars, it is a shame that the manufacturer did not provide a means to attach filters to view night sky objects.

Despite the small niggles - these are great binoculars and well worth the money.
