Celestron 20x80 Skymaster Binoculars
Celestron SkyMaster 20 x 80 Binoculars When it's time to gaze at the stars or take in some long-distance or low-light terrain viewing, look no further than the Celestron 71018 SkyMaster 20 x 80 binoculars. Featuring high quality BAK-4 prisms, multi-coated optics for enhanced contrast, a diopter adjustment for fine focusing, and large apertures, these binoculars offer phenomenal performance. The Celestron 71018 features a 20x magnification and an objective lens diameter of 80 millimeters, giving it a 4-millimeter exit pupil. (The exit pupil size - the diameter of the objective lens divided by the magnification - determines the amount of light available to your eye. The larger the exit pupil, the brighter the image obtained will be. A three-millimeter exit pupil is generally sufficient for daytime use, five-millimeters is suitable for daytime and twilight, and seven-millimeters is generally necessary for maximum nighttime or astronomy use.) The Celestron 71018 also includes an integrated tripod adapter rod, a deluxe padded soft carrying case.

This is the first pair of binoculars I’ve ever bought. I’ve only ever used my dads old pair of Miranda 10x50’s and just assumed all binoculars were roughly the same. I wanted a pair with higher magnification to view the moon.I was blown away by how much better these are and how crisp and clear the view is.They are very heavy and with this magnification they do suffer with image shake so I will be investing in a decent tripod.My only criticism is the bag they come with is very flimsy with very little padding. I would have happily paid extra for a much better quality and more protective bag.

At the time of writing this I have just acquired a pair of Celestron 20x80 binoculars at a very reasonable price. I had been observing a comet (C/2014 Q2 Lovejoy) with very good 7x50 binoculars, a 90mm f10 refractor and some other equipment. The comet was a circular blob about 20 of arc in diameter, somewhat centrally condensed and livid grass green and opal blue (in DSLR images), the same but very pale visually in the refractor, and a grayish version of same in the 7x50 binoculars... Using the Celestron 20x80 binoculars (which had arrived in the mail at 9am that morning longest day ever!), on a good solid tripod, the comet, now three times larger and much brighter, showed the colours clearly. Even the base of the tiny (purely gas) tail from this least dusty comet ... MoreAt the time of writing this I have just acquired a pair of Celestron 20x80 binoculars at a very reasonable price.

Even the base of the tiny (purely gas) tail from this least dusty comet was just visible to averted vision. The comet being in the Taurus-Aries region, I looked at the Pleiades they were superb! The field of view neither too large nor too small. So I looked for the usual suspects. The Jewel box in Crux and 47 Tucanae were breathtaking. The relaxed viewing with both eyes wide open and actively looking was great. I cannot recommend these monsters enthusiastically enough! But you need a good tripod. The 20x80s were , at less than NZD250.00, no more expensive than a good 3 refractor! I have always told students to get a good pair of binoculars and use them to see if astronomy is their thing, then move on to the 3 refractor, or a 6 reflector, etc. to do some useful work. But these binoculars - for a price no higher than good 7x50 binoculars when I last bought them may be changing the hobby at its very beginning.The student still needs the refractor (say)for the high magnification, but I can't see these binocs being "put aside". No astronomer at any level should be without a pair.

5 stars for value for the money, Celestron takes a page from a popular phone/tablet maker’s playbook by setting the stage via product presentation. The high-end and highly functional (product protection) packaging exudes the sense that Celestron is a mature company that knows what it’s doing. The binoculars themselves did not disappoint. Solidly built, we selected this model over the higher magnification 25x70 because of the included/integrated and much needed tripod mount. These binos are very large so get a tripod that can handle them. We use our job-site laser level tripod which is just sturdy enough. Did not notice any issues with optics as per some other reviews.

It's definitely worth investing in a tripod for use with these due to the high magnification. Great value for money binoculars and excellent for stargazing. Offers a brilliantly clear view of the moon and I was also able to make out the Andromeda galaxy, which was incredible to see. Would also recommend downloading a paid stargazing app to help you know where to look and what your looking for (there are a good few options available for under £5). All in all a very happy customer :)
I'm amazed that Celestron can offer so much aperture at such a reasonable price, with solid construction. I use mine mainly for specialized astronomy (observing variable stars) and find them superbly suited to that application. They are sufficiently lightweight and well balanced that I actually hand-hold them for that purpose, since most of my targets are high overhead where a tripod won't help. The eyecups are comfortable and functional, and the views are clear. I find that nighttime views of the stars are more satisfying than daytime views, which seem a bit less sharp and show some aberrations - not surprising at this price point, and I'm not complaining. Well done, Celestron!
These are just perfect for me. I wanted (needed) a pair of binoculars to compliment my telescope. These were a good price and I am very pleased with them. I have a very good (optically) pair of 10x40 which bring in so much light but I wanted more magnification and even more light collection to pick up DSO's in areas with a lot of light pollution. These binos do both but in a daylight comparison my smaller pair (which also cost 3x the Celestron's) are far superior in optical quality. However these binoculars were bought for quick 'look see' and better portability than the telescope and so far they have met the criteria. They are HUGE and they are quite heavy, if you can find the center of gravity you can hold them for a few minutes without getting the shakes but you ... MoreThese are just perfect for me.

They are HUGE and they are quite heavy, if you can find the center of gravity you can hold them for a few minutes without getting the shakes but you will need some kind of support if you need to hold them on an object for a long period of time. My only criticism is with the eye cups. Unless you're Andre the Giant getting the pieces close enough together to reduce colimation issues is difficult and uncomfortable. It would be so much better if you could buy angled eye cups that these binoculars. So far I haven't been able to source any.
I love how easy these are to use. You really don't need a telescope to look in to space! I do have one as well but it's very heavy and requires a little planning beforehand. Binoculars like these on a simple tripod is far more portable and has allowed for more spontaneous outings when the sky has been clear. Quality piece of kit for the price!
Can only be used on a tripod and thats not easy either. You need to be sat down and have binos at a workable eye level height. But they are hard work to use and very tiring at the same time. Poor focus. Totally useless for astronomy!!!!!! Pathetic carrying bag and the lens covers are hopeless. Recently saw them outside at the Minehead RNLI station as a prop for a fund rising dummy to be looking through. Just left outside in the rain! Thats the problem - they look good but they are rubbish. However to be fair to the makers they are cheap so what do you expect. A fake Rolex looks good but its not a Rolex. I fear to get a useable binocular of this spec you would need to buy Zeiss or similar and spend over 3000.00. Probably a lot more!

As always in this world, the quality of what you buy depends on how much you spend. My advice, for what its worth, its to buy an older quality second hand 7 x 50 pair of binoculars which is easy to use and will last a lifetime of properly cared for. Aim to spend around 200.00 and you will get quality.
The packing of the binoculars seemed to be well done. It took a while to get the mailed package opened, the box the binoculars came in, and then the factory carton itself. Then, I had to struggle to get the binoculars out of it's carrying case. The zippered opening of the carrying case was on the small side and only allowed for opening of the front two-fifths of the case. When pulling out the binoculars each time, the lens caps were pulled off the binoculars because of the small opening in the case. The binoculars were really huge upon first impression to myself, and to others who saw them. The weight of the binoculars really made it difficult to hold them steady barehanded. Putting them on a tripod really helped. Adjusting the eyepieces for viewing seemed fairly ... MoreThe packing of the binoculars seemed to be well done.

The binoculars were really huge upon first impression to myself, and to others who saw them. The weight of the binoculars really made it difficult to hold them steady barehanded. Putting them on a tripod really helped. Adjusting the eyepieces for viewing seemed fairly easy. Looking at certain stars and then finding that particular star was difficult with these binoculars. It would help if there were some type of gun-sight on the binoculars to aide in finding individual stars. Hooking the binoculars up to a tripod was very easy. Such a hook-up greatly aided the stablization of the binoculars for sky-viewing. The slide attachment for connecting the binoculars to a tri-pod was really handy. It would allow the binoculars to be locked at any point along a forward and backward axis of the slide-bar. However, it would not allow locking down the binoculars to prevent a tilt-rotation of the binoculars in a left/down or right/down motion. Extended viewing created a problem with accurate focusing of the binoculars. However, that may not be due to anything inherent to the binoculars. For a first time use of these, I am satisfied at present. After a few more sessions with these binoculars, I shall re-evaluate them.
Bought these for stargazing in the garden. I've rated these as excellent for the simple reason that they're value for money. You can't expect Swarovski at this price. These binoculars were above my expectations and I'm happy with what they do. They're bright and clear with sharp smooth focus. Not over heavy for the size ( they're large! Almost comedic) but if you were to be using them all night I'd recommend a tripod. Great in the daytime too but not exactly easily transportable. They're for long distance viewing and only focus down to about thirty metres so not really suited for birdwatching in a normal garden. Great for anything farther than that. I went for the 80mm lenses for more light gathering and fixed magnification because I didn't want the extra lenses ... MoreBought these for stargazing in the garden.

I went for the 80mm lenses for more light gathering and fixed magnification because I didn't want the extra lenses used in zoom binoculars. I bet the 100 mm lenses are enormous and excellent too but they're nearly three times the price and I wasn't sure I wanted to risk that much money on a brand I hadn't tried before. I would consider them now though after trying the 80mm ones. A tripod would definitely be required. Higher quality than I expected at this price.
