Product Information

Binoculars astronomical:Long range binoculars with 13X-39X magnification is designed for long distance terrestrial and astronomical viewing. This larger objective lens diameter allows for brighter and clearer images, even in low-light conditions. So to help with this, Celestron have also added a couple of thumb indents on the underside that are designed to direct you to hold them where you can get a good grip and easily reach and turn the focus wheel with your forefingers. which is fine during the day and in good light when that will pretty much match that of the size of the pupils in your eyes and so provide them with enough light so that you see a nice bright image.

ED stands for "extra-low dispersion," which refers to the composition and optical properties of the glass used for the lenses. This is less than many and so makes big adjustments comparatively quick, but also means that adjusting the fine focus is potentially a fraction more difficult than some as any small movement of the wheel moves the focusing plane just that bit further. An unbalanced bin is harder to keep steady and will also lead to fatigue over longer periods of use.There are between 10 and 18 glass surfaces within most binoculars, all of which have the potential to reflect light in an undesirable way. Because many people who are considering these will be getting them for astronomy, I thought I would pass on what you can expect to see when looking at the night sky through them. I tried this extreme and this difference did not seem to affect the eye-relief too much, so I do not think that this is anything to worry about.

Celestron’s SkyMaster Series of large aperture binoculars are a phenomenal value for high performance binoculars ideal for astronomical viewing or for terrestrial (land) use - especially over long distances. On most binoculars this grip location is also at or fairly near to the balancing point on the device, but because the barrels are so long and the objectives so large on these SkyMaster's, I found that this is not the case on these and if you simply hold them at this point with your forefingers on the top and your thumbs underneath, they want to tip forward. I can imagine that the smaller exit pupil of the 25x70 would give more pleasant dark sky backgrounds than the 15x70s in your more light polluted area.On the whole and compared to the binocular, the case is a little disappointing and even though it is a low cost binocular, the fact that these are larger and heavier than most regular bins, I would have liked to have seen a lot more padding on the case to protect them more. is authorised and regulated by the Financial Conduct Authority, register number 689922 and act as a credit broker and not a lender. For individuals who wear eyeglasses, these binoculars provide only 13mm eye relief, which can be a bit short if you have astigmatism or otherwise need to keep them on. Haven't used the lens cloth yet as I remembered from years ago to respect the lens, and so I've been too scared to go near it. However with these, it was a little different as I did not have a similar pair with me to compare them against, so I used a couple of my 8x42 benchmarks as I thought it would be interesting for those who have a standard bin, to know how they compare to these.

As with their dimensions, if you compare them to a standard full-sized binocular, they are quite a lot heavier, but as you can see from the table above they are also quite a lot lighter than many other giant binoculars on the market, even ones like the excellent and very popular Fujinon Polaris that also has 70mm objectives. degree field is narrow enough, however, that locating objects can be a lot more challenging; most binoculars provide a true field of view of 3-4 degrees or greater to make it easy to find objects as well as view the largest deep-sky targets, which may not fit entirely within a 2. The sturdy build ensures that the binoculars withstand outdoor use and the rigors of astronomical exploration. Celestron’s SkyMaster large aperture binoculars are a phenomenal value: high performance binoculars ideal for astronomical or terrestrial viewing, especially over long distances. This body shape has been tried and tested over many, many years and is one that makes for a very comfortable holding position that helps prevent fatigue when using bins over longer periods and which also helps you to keep them as still as possible for a shake free image.without lens covers and with the eyecups folded down, which is how most manufacturers advertise the length of their devices. With the rubber covering most of the body it is hard to see what the tubes of the barrels are made of, but to me, they look to be made from a polycarbonate, which is a low cost but lightweight option. Are the SkyMaster 25x70 binoculars good for imaging and observing, or would you recommend another pair?

Even though still not fully dark the contrast between sky and nebula was very good, so it was not just large to see, but stood out very well. I had previously owned a pair of the same range smaller magnification binos at 15x70 a couple of years ago but sold them on after slimming down my equipment, and whilst there are certainly better binos out there, I knew that as long as there was no problem with alignment between the two barrels of the binos, then acceptable views where available from them.I would also like to say a quick thanks to Hama (UK) Ltd, the UK distributor of Celestron binoculars for sending me these to test and review. After a few minutes I got them both sweetly in view and showing pretty easily, M81 been the easier to see out of the two, but both nicely there none the less. The included carrying case provides secure storage and convenient transport, safeguarding the binoculars from dust, moisture, and accidental damage.
