Barska Gladiator 20-140x80 Binoculars

I bought these as an alternative to my Dobsonian astro telescope, so that I could take them on holiday with me (they can easily be put in the back of a packed car with the suitcases, unlike a telescope). In that respect, they are useful. However, the optics are pretty rubbish, with alignment issues and chromatic aberrations as higher zoom. There's a blue halo around objects, and even a slight change in zoom seems to throw both sides out of focus by different amounts. Also, the maximum zoom is nowhere near the advertised 140x — compared to my in-law's Celestron Astromaster 70, looking at ships out in the bay, I'd say it's around 40x. That said, I got a reasonable view of Jupiter and its moons, the rings of Saturn, the phases of Venus and Mercury, and Comet Neowise -- probably not as good as it would have been with my Dobsonian, but I can't easily take that camping with my family :)

I use these more than my telescope. Easy to find objects in the sky

good product, works well, no defects

Good quality product .But I am returning it because difficult to use.

Clear but big. Can't hold in hand for long.

Clear, Stable and Magnified Images. First you need to tune the Binocular at Lowest Zoom Setting for the Left Eye while closing right barrel with the rubber cap, then do the Tuning for the right barrel after closing left barrel, but this time use both diaptor and focus wheels for this, after Bino pair is tuned at the lowest zoom setting, aim the pair at distant objects then zoom in and run the focus wheel until get a very clear image. If your Barska binocular is giving double images even after multiple tuning efforts, then that means your binocular pair has the collimation issue which can't fix without opening the pair which void any warranty, I mentioned this because even though Barska Optics quality is good, there are known Collimation Issues. Please remember when you at high Zoom setting your Field of View getting smaller, So depend on your requirement, you may be need a medium magnifation and bigger field of view or very high magnification and smaller field of view bino pair, this pair is best for very high magnification and smaller field of view applications even though you can have a good Zoom Out and Wider View in this pair
