Celestron 71454 Echelon 20x70 BaK-4 Prism Binoculars, Black

Product Information

With all that said about the quality of our picture framing services, you would expect our prices to be through the roof! The aluminium body feels really solid and well made and unlike quite a few other giant binoculars, these are fully water and fogproof, which not only protects them, but is also another indication of their build quality.

The ocular lenses are 25mm in diameter on these Celestron Echelon 20x70 binoculars which is pretty larger and as you may expect somewhat larger than those found on most standard sized bins in my experience. Another quite important difference between these high end Celestron Echelon binoculars and the entry level Skymaster's is that the body on these has been fully sealed and they are described as being waterproof, whilst the Skymaster's are not. The eye-relief is really long, which for those who wear glasses whilst using bins is really important and their field of view is pretty good and up there with other 20x binoculars. APM Binoculars have a magnesium chassis, the lightest of metals. Magnesium isknown for its strength and its resistance to corrosion. The binocular bodyis also covered with a rubber coating, protectingthe binoculars further and allows for a secure non-slip grip.

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. As we know these come with large 70mm diameter objective lenses combined with an also reasonably powerful 20x magnification. Both these attributes affect how they perform optically, especially when we consider how well they operate in sub-optimal light conditions:

Computing

I think it is also important to stress that the opinions and the conclusions that I come to after testing are my own and are honest. If I like something I will say so and if I don't that will also be highlighted. The manufacturers know this when they send me their products to review and I am never in any way encouraged to act in any other way. 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. Keeping in mind that my 10x42 benchmark has an exit pupil of 4.2mm (42 ÷ 10) and these have a 3.5mm (70 ÷ 20) exit pupil, it is not surprising that even though it was quite difficult to tell because of the large magnification difference, I did think that my benchmarks were brighter in low light, but the difference was not huge and you do of course get a much more detailed image with these Echelon's. This also means that you do not have to opt for a Celestron branded adapter. I have used a Celestron adapter in the past that came with the SkyMaster, which was ok, but because it plastic, it did have a tendency to twist a little under the increased weight of a giant binocular. So for the best results I highly recommend that you ensure that you get yourself a good quality metal tripod adapter, see my section on binocular tripod adapters here for more info. Whilst I have already mentioned how well balanced the Celestron 20x70 Echelon binocular is and even with the high power and the fact that it is fairly heavy, it is still possible to use it very effectively with only your hands. However in some situations (like viewing up into the sky) or if you need to look through them for longer periods or if it is imperative that you have a very still image, you are going to want to attach this binocular to a tripod.

These special coatings are added to the glass surfaces to increase transmittance levels, for a brighter image, but also improve the view by eliminating unwanted reflections that can cause undesired results. Echelon binoculars use an individual eye focus system, enabling you to rotate each eyepiece to set the proper focus for your right and left eye. Once set, you should be able to use your binoculars at a moment’s notice and focus sharply at infinity, the normal distance desired for long-range observations. Should you wish to share your binocular with others, it is fast and simple to adjust the focus for their vision requirements.

Calculate the Square Foot of Another Room

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.

Also included are details of the lifetime warranty and what you need to do should they need any servicing or repairs. 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 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 Silentnight Deep Sleep All Seasons Duvet has been specially created to help you sleep more deeply throughout the night through every season. One of the biggest causes of sleep disturbance is overheating. The Deep Sleep All Seasons duvet allows to you easily switch your togs so you can stay asleep for longer. This clever design consists of two duvets that can be used in three different combinations. So, whatever the weather you will have the perfect duvet to help keep you at the right temperature. To create the 13.5 tog duvet, use both the 4.5 tog and 9 tog duvets fastened together which will result in a duvet that will keep you cozy and warm during colder months. Alternatively, you can pull the duvets apart and use the separate togs individually in warmer months to keep you cooler. For convenience, you can easily pull the duvets apart using the popper fastenings. The 4.5 tog duvet is ideal for warmer summer months, while the 9 tog duvet is great for all-year-round use. Both duvets have been generously filled with hollow fiber which creates a soft, cozy, and lofty duvet. The polycotton cover is comprised of 80% polyester and 20% cotton, giving you the durability of polyester and the comfort and breathability of the cotton. Silentnight is the UK’s most trusted sleep brand with over 70 years of experience in creating products to help the whole family get that ‘great sleep’ feeling.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! So the observations below are based on my experience and my comparisons to my high end benchmark 10x42 binoculars are there for interest: 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.
