A slight difference to the norm is that rather than having a single wide central hinge, these Celestron Echelon binoculars have two thin arches that span the gap between the barrels, which I guess helps a little in reducing weight and because they are metal and not plastic like some I have seen, there is no compromise on strength.

The the foam inner is cut-out to fit the binoculars perfectly and once closed and sealed the case is also waterproof as it has a rubber O-ring around the lid, so not only are they protected from fairly large impacts, but also from dust and moisture as well. One of the big improvements between this Echelon and the SkyMaster is the fact that these have Fully Multi-Coated optics, whilst the Sky Master's are only Multi-Coated.They are pretty simple and don't have a loop or another way of keeping them attached to the binocular when not in use which is a little bit of a shame as after a time it does become somewhat painful having to find and replace them after every use. So what often happens is people eventually leave them off, which in turn means dust gathers on your lenses, which means more frequent cleaning is necessary and the potential to damage the lenses or coatings.

The published width is 22.2cm (8.74in), this is with the hinge fully open (IPD set to max), this width can reduce to 20cm when you close the hinges (IPD set to minimum). Meranti hardwood timber PAR (Planed All Round) with a natural medium dark reddish-brown colour and light grains, is the most commonly known and used hardwood in wood working. Meranti hardwood timber PAR is precision machined, finely selected and graded to ensure it's free of any major natural defects. Its good quality characteristics offer many applications such as windows sills, furniture, facia, cabinets and other joinery projects for internal and external usage. There is broad range of sizes available to choose from which will suite most domestic and commercial wood work projects. Meranti hardwood can also be varnished, stained and treated as required. However remember that these Celestron binoculars are designed for long range observation and so for the most part, your focus will be set at infinity which means that you can use them instantly without having to make any further adjustments. The only time you will have to alter this is if you wish to look at nearer objects or if you were to share the with someone who perhaps has a different vision requirements to your own. So with frames in a wide range of styles at up to 55% off high street prices, all in one place, there's no need to go anywhere else than Frames.co.uk. The calculation to work out the square feet of both a square and rectangular room like 20x70 is very simple. All you need to do is multiply the length by the width. Square Feet = Length x Width 20 x 70 = 1400

Whilst Celestron are best known for their telescopes, they also produce a number of standard daytime and astronomy binoculars. Their very popular SkyMaster series is aimed at the more budget conscious user (for example see my review of the Celestron SkyMaster 25x70 Binoculars), whilst the Echelon series that are put together by hand in the USA using high end Japanese optics is focused more on quality: material quality, build quality and the image quality. All Echelon series bins, including this model use a individual focus system which essentially means that you need to focus each eyepiece individually by setting the diopter, which simply means turning the eyepiece. We manufacture picture frames in a wide range of colours, materials and finishes to suit every home. Celestron also highlight that the prisms are made from BaK-4 glass that in most cases is considered to be as good as it gets on a binocular. Optical Coatings When your size of your pupils are the same size or smaller than the exit pupil (In good light conditions), it is not a limiting factor. However when it gets darker and your pupils dilate, bins with smaller exit pupils will seem less bright than equal quality ones with larger shafts of light exiting them.

To try and get a consistent opinion, I like to compare the view I see through the binocular under review with that of a similar benchmark binocular of mine. I have a number of these in most standard configurations, unfortunately as of yet, I do not have a giant benchmark binocular. Apart from the typically elongated barrels found on most on high powered binoculars, the overall shape is essentially the same as that of most porro prism bins with the eyecups being closer together than the objectives. Whilst this traditional body shape is necessary due to the design of the roof prisms and the way the light passes through them, it also happens to make for a fantastic ergonomic shape that feels very natural as well as comfy and secure to hold in your hands. These really are a great pair of long distance and astronomy binoculars. The higher price may put off many casual observers or those newer to the hobby but for those who are more serious and/or are looking for a great quality view then these really are hard to beat and a big improvement on their SkyMaster Series in my experience. Our frames come in any size, so you can search any size picture frames or browse our popular size frames.

It takes just under 1 full rotation (360°) of the eyepiece to take the focus from infinity to it's minimum close focus of 328.1 ft. /100m. The turning mechanism for each eyepiece on my test pair was nice and smooth, but with some resistance that eliminates any unintentional turning. What is more, there was absolutely no free play or movement in either eyepiece which was great and shows just how well they are made. Don't forget our experienced framers are here to help Monday to Friday 9am to 5:30pm on 0161 962 5573. Even if you never take them outside, having a sealed and fogproof binocular is important. Firstly it is another indication of a bins class and secondly, remember that as well as liquid and moisture, it will prevent dust and other tiny particles from being able to get inside and potentially spoil the optics and your view. Ideal For: Whilst these are obviously quite a bit bigger and heavier than your average birding binocular it is still quite possible to hand hold them and use them in some situations, even with the massive 20x magnification. Thus with or without a tripod, I can see them being very useful for a wide selection of long range terrestrial uses and of course as a great set of astronomy binoculars.

Celestron also include a cleaning cloth, that is fine for emergency use out in the field of for cleaning the body with. But for regular and proper care of your lenses I highly recommend that you invest in a specialist optical cleaning kit. To see exactly what you get at this higher level and if they are indeed ideal long range, low light and astronomy binoculars, take a look below at my Celestron Echelon 20x70 binocular review that I wrote after fully inspecting and testing them out on location and which goes over all the features, components and my opinions on the image they produce. Where relevant, I also highlight the differences between them and the SkyMaster's: This tends to let me conclude that for a high powered bin like these, these are pretty good low light performers. Sure a super giant 20x100, would be even better, but you just try and hand hold one of those! Our large team of trained picture framers take great pride in the quality of their craftsmanship and to assist with accuracy the majority of our machinery is automated,It is always good to have a binocular that is well balanced as it makes it much easier to keep completely still and use over long intervals, but with a large binocular like this with a powerful magnification, balance becomes a very important feature when using them without the aid of a tripod: You can use this guide to calculate the square footage and cost of a building, floor, walls, and more. On some bins you get a large region around the edges of the view that is a little fuzzy. This amount of softening varies, with the best ones having almost none at all. I would say that whilst these are not the best I have ever seen, they sit near the top and the amount of softening that you can see is really not important and honestly only really noticeable if you are actually looking for it.
