They boast high-quality optics with multi-coated lenses and BaK-4 glass prisms to provide clear and bright views.

The rubber coating makes them water-resistant and easy to wipe clean, but it also gives you an excellent non-slip grip enhanced by small rubber pimples where you hold the binoculars. During the day these are good for wildlife watching and are helpful in bird hides to see far-away subjects, especially waterfowl because their graceful, slow paddles make them easy to track. If this filter says "No", but you would like to use a tripod, there are a handful of adapters that wrap around the binoculars instead of threading into a 1/4-20 built-in port.The focusing wheel is similarly smooth and fast enough to pull focus to subjects, whether they be stars, birds, or planes. We found that we couldn’t quite get them close enough together to feel 100% comfortable and we can’t really see a reason why they don’t, with only a bridge of plastic spanning the two tubes locking together that stops them from coming together slightly more.

Today, our world-class team of optical and electronic engineers continues to push the boundaries of technology. Generally, eye relief should be at least 10 mm, but you will find that about 15 mm will provide best comfort without glasses.Eyecups are foldable, but offer very generous eye-relief, and you can make it perfect even for eyeglass wearers. The binoculars are large as we would expect for something of this magnification and with objective lenses at 60mm. Radio2Space radio telescopes are such products and these are only available through 365Astronomy in the UK.
