Celestron SkyMaster 20X80 Binocular

First thing first, delivery service, packaging was great. This is my first binoculars ever. So I can't say if this piece is completely out of collimation (will give updates once I check). Pros: 1. Well built. 2. Fully multicoated optics. 3. Value for money. 4. Best for beginners in Astronomy. Cons: 1. Quality of the bag provided is not good. (substitute would be a DSLR camera backpack and it will do the job). 2. Collimation could be a problem. (Almost all heavy binos have this error). You can fix it yourself or could ask for a replacement. In detail:- 1). You cannot get this quality at this price. Compare with ORION 20X80 --- which is around ₹ 25k. 2). If you cannot decide about getting 20X80 or other smaller binos then I would say 20X80 would be better. It has a larger objective of 80mm which increases your limiting magnitude to approx +7(with naked eyes your limiting magnitude is around +1). That's a huge difference. You will be able to see most of the messier objects and other DSOs apart from Moon, planets, and Orion nebula. 3). It is literally a pair of two small telescopes😉. A telescope equivalent to these binoculars will be above ₹ 30k (trust me), So this is a great deal. Some important points: 1). You can adjust the interpupillary distance. (As any other binoculars have) 2). You can adjust the dioptre setting (for individual focus adjustment for eyes) by rotating the right eye piece. (please Google for more information) 3). Centre focus wheel is given. ( For focusing at different distances) (All above three adjustments could be stiff in the starting) Suggestion for Tripod: 1). A fluid head tripod is a must (for smooth and precise maneuvering of binoculars). 2). Tripod must be heavy (to keep binoculars steady/ 20X magnification is too much). 3). A branded tripod is not required. 4). I will suggest getting a tripod from a photo store. (If it's in your budget then Manfrotto fluid head tripod will be the best) An Update: 1). Saturn's ring is visible. It will need a nice focus and patience. 2). The object should be at the center of the field of view to avoid chromatic abrasion. 3). Four of Jupiter's moon are visible. You can not make out the Great Red spot. 4). After watching planets for an hour, I found my binoculars are perfectly collimated. 5). Bright objects (-2 magnitude or higher) will give chromatic abrasion. 6). You will be able to see stars as dim as +8 magnitude in a light-polluted sky. 7). Andromeda galaxy will cover your entire field of view on a very dark night. 8). Many DSOs around the Sagittarius constellation are visible from these binoculars. 9). The field of view is around 2.6° and not 3.7° as mentioned. 10). The moon looks breathtakingly beautiful. It will appear three dimensional with these giant binoculars. You can make out Apollo missions' landing sites to a precision of few kilometers. 11). Orion Nebula will be visible bright and crisp. Your field of view will be contain just the Orion sword. 12). If you are willing to do astrophotography using these binoculars then you will need a smartphone adapter for binoculars (just search for it and you will find it on amazon) and a photo staking software - DeepSkyStacker which will stack together hundreds of shots of a DSO and after few hours of processing, you will get a bright and detailed astrophotograph. 13). Neptune and Uranus are visible just like a dot but you can make out their color. Best at this price!! Clear skies!!

Guys, this is a honest review. I bought it for 13500 INR combined price on 12th of july 2020 along with digitek 880 pro tripod, in conjunction they work fabulous. I have used it for a month and a half till now, since I had early experience with star charts , star gazing apps and nautical astronomy from my college, it became easier for me to do binocular astronomy with these huge ones! Trust me, I belong to Hyderabad rated class 9 on bortle scale and I have seen upto 10 dso's which obviously looked faint due to light pollution at my place. We can easily make out Jupiter and its four moons. No offense but Jupiter looks just like a bright dot. Saturn's disk can just be identified under keen focus. Sunset visuals and the moon looks breathtaking awesome! I was also able to see Neptune as a red faint dot. I have also used them for bird watching (eagles) and terrestrial spying too. These activities are always fun with them. Every experience through celestron skymaster 20by80 will widen your eyes open. It is not so big as 25by100 and also not so small, being perfect for an amateur astronomer, tripod is compulsory(as they weigh 2.1kg)! A photography tripod works best. Handle them with care and they may serve you many years and I can't wait to get to a dark night sky and visualize milky way through this binoculars. Get a mobile adapter and adjust your camera settings to capture amazing images of celestial objects. As far as I know, this is the best binocular you will get at a cheaper price of best quality. Happy stargazing and clear skies!

The binoculars arrived in good condition and they were properly collimated. These binoculars are relatively lightweight for their size; don't mistake me, they are not meant for hand-holding. They need to be mounted on a sturdy tripod. I am using it on my Gitzo tripod + Markins ball head; works good. Positives: Physically they seem to be fairly sturdy. The objective diameter is 80 mm as advertised. They seem to be multi-coated; they show a pale green reflection against light. The inside of the barrel is corrugated and properly blackened. The exit pupil is well rounded. There is no cutoff of exit pupil, nor there is any detectable vignetting/light fall off. I viewed many deep sky objects with these and thoroughly enjoyed the view. Negatives: Brighter stars not pin-points even at the center of the field, they exhibit spikes like diffraction spikes of a newtonian. But for fainter starts this is a non-issue. The rubber eye-cups are a bit hard. For my interpupillary distance the eye-cups are so close that I cannot fit my nose between the eye-cups. Hence I am not able to place my eyes close enough to get a full field of view with eye-cups up. When I fold down the eye-cups I can enjoy the full filed of view. The eye relief does not seem to be 18 mm as advertised, It seems to me closer to 12 - 14 mm. I have not measured it though. The filed of view is close to 3.2 deg, not 3.7 deg as advertised. There is colour fringing on brighter stars. I haven't had an opportunity to view moon through them. When mounted on tripod, even after the top knob is fully tightened, the binocular yaws a bit to left or right. Finally, the bag supplied is of poor quality. It does not provide much protection to the binoculars. Still, these a pair of good binoculars, capable of providing hours of joyous deep-sky views under dark skies. They are value for money.

Not at all Hany. This not at all suitable as Binocular for the binoculars are generally to hold in hands. This is almost 2Kg. of weight. One cannot hold in hand to Watch anything at any upside angle holding in hand. It shakes due to huge huge weight. How can you see your target patiently in that case? Its needs a tripod but that's not a handy way.

Not much handy. Interesting just to watch the moon and nothing else.

10/10 for product quality The visual through this powerful binoculars has no comparison in 13-15k price range. Best for amateur stargazing as well as terrestrial use. The image is sharp and clear, nothing compared to the picture i have uploaded using my phone and some editing, the actual view is far better. It would have been better if it had little more zoom upto 25x but still its fine. Can see more stars than u can through unaided eyes. Tripod is mandatory as it is around 2kg, cannot hold it for much longer. I would suggest everyone willing to buy this binoculars should also buy a mobile adapter for clicking pictures if interested as it’s very hard to hold the phone steady enough to focus and click pics. Note: images above are clicked through iphone 8 without a mobile adapter. It will be your companion for long if taken care.

This binocular is just awesome! You will get splendid view of night sky! You will certainly require a heavy duty tripod! Its quite heavy,so you can't hold in your hand for even a minute! You loose focus quite easily! It fits in my expectations! Good for astronomical purposes! Clear skies!

Everything is great about it, although huge and bulky, gives crisp images, but I had to return it as soon as I came across an ergonomic issue. The best place to look for clear skies is straight up, and while seeing through these have to extend my neck for a long time and it gives neck pain, as opposed in a Telescope this issue gets resolved as we usually see at 90 degree. One would argue that we can lie down and mount the Binocs on a Tripod, but it becomes a little cumbersome. But what I do like about it was it gives Crisp & clear images, but get a sturdy Tripod for it. Moon and it's craters seen clearly, rather very bright. Pleiades could be seen directly without a tripod. Overall a great product to have, with Crystal clear optics. Have ordered a Orion Skymaster 100mm reflector Telescope with Dobsonian table mount instead, hope I made the right choice.

Upgraded my SkyMaster 15x70 binos to the 20x80 model. This review concerns astronomical use, especially as it relates to casual observation. I just returned from two evenings with it under the dark skies of WV's Monongahela National Forest 1) Field of view offers wide angle eye candy. 3.7 degrees with the feeling of expansiveness--even at 20x. I could place Orion's belt in one view; Orion's sword in another; The entire Pleiades (M45) in one glimpse; much of Kemble's Cascade; nearly all sections of the Veil Nebula complex; The Lagoon (M8) and Trifid Nebulae in one field; Can almost place M7 with M6 in Scorpius in the same field, also the Coathanger asterism fits nicely into the field of view. 2) Spectacular views offered of M7 near the Scorpion's tail, The Swan nebula (M17), Dumbbell Nebula (M27), a billowing Orion Nebula (M42), Pleiades (M45), Andromeda Galaxy (M31) with companion galaxies...can seem to infer some stars on the outskirts of globular clusters M13 (Hercules) and M22 (Sagittarius). Veil Nebula is breathtaking under dark sky (t5he western side resembles a fuzzy fish hook). Can see North American Nebula near Deneb at top of Cygnus. I returned to several of these again and again--so rewarding were the views. I set it up a week ago for a backyard star party and the Pleiades was really impressive for viewers as was the Perseus Double Cluster and Albireo double star. The Orion nebula is also magnificent. 3) Generous Eye Relief is best utilized by folding the eyecups back 4) Used a 30 year old aluminum camera tripod that is sturdy enough to hold the 20x80 with ease. How I found it effective was to sit in a wooden kitchen table chair with the tripod legs fully extended and tripod close in with bino eye cups folded back. My tripod has a shaft that can rise about 10 inches more so I used that incrementally as viewing angle was increased--not unlike a barber's chair raising or lowering. Ample eye relief coupled with the folded back eye cups and raised tripod slant the bino was attached to meant I could view objects 45 degrees up from the horizontal. Objects near vertical I could manage limited viewing by actually leaning back with binos and tripod legs laying across me. That's how I viewed the Veil Nebula. Be mindful of the weight before trying this!! It was OK for me but may not be for you. Test that carefully. The 20x80 mount is more robust than the attachment I used with the same tripod with the 15x70's. 5) Clarity of image was NOT sharp all the way to the edge. However, for the comparatively low price of the 20x80 I really can't complain about this as I'd pay much more for that level of optics. 6) I have an 11" SCT telescope. The 20x80 is a nice, satisfying casual alternative to setting up my larger scope and I had so much fun with it one evening I never bothered to set up my SCT. 7) These binos are HEAVY so a sturdy tripod is recommended. The 20x80 is significantly heavier than my 15x70 set. I can use each hand held on their own for limited viewing by gripping the large ends with each hand. 8) The moon is not excessively bright as it tends to be telescopically so you need not be overly concerned about temporary "blindness" from viewing the moon then switching to other stellar objects. Eye recovery is but momentary. 9) Did finally view Jupiter. The line up of the moons is more as one sees telescopically rather than with traditional binocular views. Be advised that surface brightness is so great one will likely NOT be able to the bands on Jupiter. Mars and Jupiter are definitely bright discs. haven't yet had a good look at Saturn as its currently near the sun in the sky.

Beautifully clear image offered by the large 80mm lens. They have a robust feel and seem to be well made and should last for many years with care. These are a great starter pair for sky watching, but if that is your main use for them you W|ILL need a Tripod. They are heavy but thats not the real problem, if you focus on anything that is on considerable magnification it is impossible to hold them still enough to get any sort or real idea of the target image, in addition as soon as you try and adjust the focus, you loose the target you are focussing on. I bought these as a powerful set for sky watching, birding, and general scenery when walking and holidaying. Though bulky they are worth carrying for the quality and depth of the image that is available. Easily backpackable. I live in a city and it is amazing the way on a CLEAR night they cut through the haze that is there (but not visible) and allows you so see a complete vista of stars that are not available to the naked eye. I wish I could have afforded the 25x100, but for that cost I will supplement it and buy myself a good telescope. These are fantastic powerful general purpose binoculars and can be used for sky watching WITH a tripod, dont believe reviews that say you dont need it. Great Value. Recommended. I wish they had provided a better padded carry bag.

I thought that the magnification is really good

O que dizer de um binóculos que traz as maravilhas do céu até seus olhos? Alguns meses atrás comprei um 7x50 da mesma marca e após varrer boa parte do céu, senti a necessidade de um upgrade. Apesar de o 15x70 ser mais barato, resolvi ir de vez atrás de um maior e deparei com esse 20x80. Arrependimento? Apenas com o tempo de espera até chegar, passou pouco mais de 1 mês até ter em mãos. Já o binóculos em si é sensacional, não tem comparação com meu 7x50 quanto à observação do céu. Obviamente não é possível ver detalhes dos planetas, mas Titã é visível, Saturno aparece como uma luz alongada e Júpiter é majestoso com seus maiores satélites, imponente no campo de visão! Notam-se muitas crateras e montanhas na Lua com uma qualidade incrível! Além disso é possível ver também aglomerados estelares, nebulosas e algumas galáxias, porém dependem pelo menos de um céu rural. Falando em nebulosas, a Carina e a de Órion são as mais lindas para se ver, na minha opinião. Para se ter uma ideia do que é possível enxergar, no centro de onde moro cheguei a identificar, com muito custo, estrelas até da magnitude +10.2, sendo mais fácil identificar até mais ou menos +9.5. Já objetos menos densos, como nebulosas e cometas, dependem muito da poluição luminosa e não chegam a tal magnitude. Como nem tudo é perfeito, há alguns pontos negativos: 1° - a aberração cromática é bem forte nos objetos mais brilhantes, mas não chega a comprometer a experiência. 2° - por mais que na embalagem diga que serve para visualização terrestre de longa distância, não gostei da falta de nitidez nos morros ao longe. Nesse quesito ainda prefiro meu 7x50. No geral, é um equipamento indispensável e ótima alternativa aos telescópios baratos. Mas tenha em mente que é praticamente exclusivo para astronomia.

手持ち出来る低倍率双眼鏡ばかり使っていたので多少倍率が大きなものが欲しくなり、最初は廉価なトラベルスコープを検討しました。 しかし、同価格帯にこれがあることを思い出してからは無性に欲しくなり注文後5日で届きました。 並行輸入品ですが、製品自体スチロールの型に収まって箱に入っており、それが更に二重に梱包されていたため全くダメージはありませんでした。 早速手持ちで覗いてみましたがさすがにブレてよくわからず、三脚に乗せてやっとピントと光軸確認できました。幸いな事に星がきれいな点になってくれます。 また丁度晴れたのと気温が低めだったこともあり、80ミリの集光能力だと殆どどこに向けても星が見えます。 街灯などの影響は多少ありますが思った程ではなかったです。（Vixen旧アスコット（7×50）の様なフレアは出ません。比較対象がなんですが） ただ20倍となると安物カメラ三脚では三脚や双眼鏡にちょっと触れただけでもブレてしまいますので中央からおもりを釣り下げて安定させようと思いますが、昼間の地上であればそれほどシビアにはならないので車に積んで見晴らしのいいところで周囲を眺める使い方の方が増えるかもしれません。 こうなるとまさに我が家の100円望遠鏡（観光地にあるアレ）ですね。 このモデルはこのサイズの光学機器としてはかなり安物ジャンルに入ると思いますが、こういった使い方には十分な性能ですし、お値段以上に楽しめそうです。末永く使っていきたいです。 2019/02 この双眼鏡用に廉価で安定した三脚を入手しました。 →アマゾンBASIC ガングリップ雲台つき三脚 約３千円 最大地上高180cm程あり、この双眼鏡をかがまないで覗けます。 （高さと強度が両立して廉価なものは少ないです。） ただし、元々ついているガングリップ雲台は仰角が大きくなる星見では接眼高さが大きく変わり使いにくいので、3/8ネジの低めの自由雲台に取り換えて使っています。 ご参考になれば幸いです。
