About this deal

They are adjustable for eyeglasses wearers up to 17mm but are of the flip-down variety and we’d love to see these follow suit with some of Celestron’s other binoculars and have twist-down eyecups so that those who require it can fine-tune their placement during use.

All the models offer central focusing mechanism with grippy wheel that allows you to make quick adjustments with the help of right-eye diopter. We have spent a couple of weeks trying them out and we think they are an excellent choice for amateur astronomy, bird watching, and nature spotting.Multi-Coated: This term means that the binoculars are Fully-Coated, and on top of that, at least one side of a major lens element is coated with multiple layers of anti-reflective material. While there are certainly individuals who don't require a pair of waterproof binoculars, we recommend it for most people.

As we discussed earlier, they are roof prisms, which are inherently more compact than the Porro pair in this review. They are also equipped with objective lens covers and eyecups covers to protect the lenses, but are not included in smaller roof prism models. Fine (if a bit annoying) in the daytime, but in the dark, we found a few occasions where they fell off without us noticing, and we needed to use a headlamp to locate them. Linear field of view is the width of the area you can see through your binoculars and is usually measured in feet observed at a distance of 1000 yards, i.And ‘cheap’ Porto prism bins usually suffer that ‘back and forth’ focus necessity as the focus arms are rarely slick enough to avoid some slack (probably the reason for the tight main focus wheel, to keep the arms in as ideal a plane as possible. This is expected but possibly a little frustrating, especially when using on a tripod where you may not want to keep centering your target. This high-density glass offers much better optical quality than the less desirable BK-7 glass that is generally found on very basic models, giving a better low-light performance.

Using a tripod when observing for longer periods of time or at high magnification (or both) helps keeps the image shake-free.Unless, of course, you plan to mount your binoculars on a tripod, monopod or other type of support, then the weight doesn’t matter. The pocket sized binoculars have a roof prism design to make them more compact and light, and bigger models have a Porro prism system to make them brighter. The build quality of the binoculars is excellent, and the whole body is protected with a black rubber coating with some Celestron-typical orange branding. However, we’re splitting hairs here as they are much cheaper than many other binoculars and have good performance where it counts.
