Celestron 71018 SkyMaster 20x80mm Porro Prism Binoculars with Multi-Coated Lens, BaK-4 Prism Glass and Carry Case, Black

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've been the owner of a pair of 10x50 Tento binoculars for years, so I decided to upgrade and treat myself. I looked very carefully at each Celestron Skymaster binoculars available to see what might suit my needs. After doing some research and checking each spec, I decided to opt for the 15x70 Skymaster and boy does it do what it say's on the tin. Excellent clarity, great field of view and surprisingly not as heavy as what some people would say. Granted, without a tripod (which I might purchase in the future), they can feel a little heavy after a while, but if you place your hands at the end of the binoculars by the objective lens, the weight kind of balances itself out nicely. Setting up and calibrating the Skymaster to your eye's is very simple. To be honest, unless you are a serious sky watcher, don't get anything bigger than this as your field of view will be seriously decrease and you will need a tripod. 15x magnification is what I would say is in the Goldilocks zone. My Skymasters arrived less than 24 hours after I ordered them with standard delivery and that was without Prime. There was a crescent moon the same night and boy was I blown away. I could see far more details than I ever could with my old pair of bino's. At this price, the build quality is awesome and feels way more expensive than it's price. Just a good bit of advice though which I found when I was doing my research, if you do buy a tripod, purchase a metal tripod holder for your bino's as the plastic one supplied is pretty much useless as your binoculars will bounce at the slightest touch, spoiling your view time, but a metal tripod holder will keep your binocular as steady as a rock.

I bought my 15x70's a couple of years ago as a back-up to my Telescopes for star-gazing! Sometimes the weather doesn't give much time to set-up a scope whereas the binoculars are ready to use at any time: only problem is the weight! After a few minutes the arm strain becomes unpleasant! Using a tripod and adapter does over-come this problem but defeats my original reason for buying them in the first place! However, I have found that lying in a deckchair, or leaning back against a wall, with elbows resting on chest I can support the binoculars for much longer periods without discomfort. While not ideal for viewing planets; Jupiter can be resolved with the 4 Gallilean moons, Saturn can be seen with its rings but little detail, the moon provides endless fascination but can leave you with "Snow-blindness" near to full-moon. Where these binoculars excell is in finding star clusters, the Pleiades look quite stunning! Nebulae and some of the larger galaxies are visible as smudges, some structure can be seen in some and a hint of colour in others. Where my binoculars have come into their own is on holiday: I frequently sleep outside in hot climates and can view many of the sights that are hidden from northern latitudes. They are great for day time use also; whether spying out distant ruins, whale or dolphin spotting, or even just watching those huge cruise liners in the distance. (Note: take as hand luggage on a plane to prevent moisture forming inside!) When unpacking the binoculars for the first time you will find a strange lump of plastic, described as a tripod mount: DISCARD THIS IMMEDIATELY: it's worse than useless! Camera tripods are generally too flimsy to take the weight of the 15x70's but with a good metal Adapter Visionary Heavy Duty Black Metal Binocular Tripod Adaptor - Standard 1/4" Tripod Fitting On Underside - Fits Most 'Traditional' Style Binoculars - Ideal For Very Large Bulky Binoculars and a good quality tripod ~ HALF PRICE ~ Tripod Universal Folding Good Quality Stand for Digital Camera Binoculars Telescope Spotting Scope SLR Camcorder Astronomy Stargazing & Photography Collapsable with Carry Bag 166cm Tall or 65" Inch High Pan Head Quick Release Fits all mak... they become quite manageable. The lenses are coated for night time use which allows excellent light transission to the eyepieces meaning that they work very well in low light conditions: the lack of lens-front reflection means that highly reflective surfaces (e.g. the sea) can dazzle. It might sound daft but the eye-cups allow the user to view through sunglasses during the brighter parts of the day! Excellent introdution to astronomy at a reasonable price, yet versatile enough to be used else-where. Lens quality is good and construction solid: I've now had 2 years of use in all conditions from -30c to +45C, sea level to 3,000 metres and it's never let me down; definitely money well spent! If you are looking to use this for astronomy I would suggest you add a Planisphere Philip's Planisphere (Latitude 51.5 North): for Use in Britain and Ireland, Northern Europe, Northern USA and Canada , a red LED torch OVL Dual Beam Astronomers Torch and a good reference book Astronomy Manual: The Practical Guide to the Night Sky or Binocular Astronomy (Patrick Moore's Practical Astronomy Series)

No I didn't spell it wrongly. I am an occasional sky watcher not an avid star gazer. I carry a pair of binoculars in the car to stop and be nosy from time to time an do a few minutes of bird watching if something catches my eye. I asked for a decent (but not expensive) pair of bins for Xmas but was not trusting my wife enough to let her loose on Amazon. I am on the downhill side of life (along with my eyes), I have imbalanced sight and astigmatism in one eye. I researched many Celestron products and some users were critical of bad collimation. These 25x70s were pretty well reviewed and at a very reasonable price for such a high mag product. I noted that some people thought them heavy and were only usable on a tripod and others were critical of the plastic tripod mount. I already had a decent video tripod but made sure I asked for a steel bracket as part of the present. They turned out to be a great Xmas gift and I have used them several times in the last month. Easy to focus and to balance out my eye problems. Heavyish, yes but manageable for a few minutes. Looked at planes flying overhead.....the narrow field of view makes it difficult to pick things up quickly. I scanned across the con trails and then followed the trails to the airliner. Amazingly close and crystal clear (great if you are a plane spotter, which I'm not) but you need to to be hand holding to follow moving objects like this. Left them outside on a tripod for an hour on a cold clear night recently (so that they didn't condense up on coming from my warm house) and then looked at a few stars. As I mentioned earlier I am no astronomer so I was amazed to see a cluster of small stars around a pinkish bright star in the eastern sky. A quick Google search told me I was looking at Jupiter with its moons, surprisingly clear. Our local moon was almost too bright, it completely filled the field of view and was crystal clear. A real wow moment! Great product, fulfills all my requirements for casual close-up viewing. The carrying case is a bit flimsy but fine for the car. Not a set of binoculars to go walking with but would be great if you owned a submarine or battle cruiser.

My Celestron Skymaster 20x80 binoculars were received a few weeks before Christmas, but as they were a Christmas present bought for me I didn't get any chance to test them out before they were all wrapped up ready for the big day! So now I've had chance and these are my findings after using them for about four or five hours solid. Firstly, I can confirm that mine were NOT out of collimation. I'd been reading all about collimation as a number of people on the net had reported this problem with various Celestron binoculars (and others) so I did absolutely loads of research on the net in case mine needed collimating. In a nutshell, collimation means that the prisms are slightly misaligned causing a sort of slight doubling of the image. Apparently, the manufacturers of Celestron binoculars in China don't have the best quality control system in place and it seems that unfortunately some of these models ship already out of collimation. If you don't know what to look out for chances are you'll just put up with it as it can be barely noticeable, but it can cause eye strain and headaches as your eyes try to 'correct' the image. So, I've been lucky with mine as they are certainly not out of collimation. The image through the 20x80s is great, nice and bright and I found they snapped to a good focus. Focusing on a dark vertical post against a bright sky background revealed a little color fringing, certainly not enough to be a problem, but this will be present in just about any binocular optics anyway unless you go very expensive. All movable mechanisms like the focus wheel and the dioptre (right eye piece) adjustment are nice and smooth with no sign of stiffness thoughout it's range. Finally I thought I'd mention the weight issue as a lot of people mention this. They are pretty heavy yes. unfortunately this is a trade off for the large 80mm objective lenses. If your only using them to grab and use for just a minute or two before putting them down again then you really shouldn't have too much of a problem, but then I'd have to wonder why you would go for something of this size and weight if you never plan to use a tripod. Mounting them on a tripod is without doubt where you will appreciate them most, especially as this is what this model is designed for with the built in tripod adapter. Had a good look at the stars during a brief break in the clouds and it was great. Now looking forward to clearer skies and getting away from all this light pollution. I hope this helps a little. I'm really pleased with mine and wouldn't change them.

Skyviewing ..yer cannot beat these binoculars Relatively high price tag but as they say "You get what yer pay for" ....£29.99 binoculars with wonky wobbly prizes dont cut the mustard These bad boys not only cut the mustard but manufacture it sell it & help you eat it !!!! Top top class, invest in a pair of these & you'll instantly know yer previously purchased pair were fit fer the trash can 2 minutes after you'd open the packaging! MY ADVISE IS...BUY THEM YOU WILL NOT BE DISAPPOINTED

Just to start off, these are superb. I bought them for star/planet gazing. Bro, while Jupiter is visible from my backyard in North London, I looked up with these and saw the wonderful sight of Jupiter and three of its satellites. Unseen with my naked eye, but clear as anything with these. Seeing all the details of the Moon, like so many craters, clear as anything. I now need to invest in a better tripod than the one I have. When holding them, I'm not very stable, but I found that using the tripod accessory (see pic) as a holding apparatus keeps me more stable, making it easier to focus. Black friday deal helped me to be able to afford but worth full price if you ask me. Sturdy high quality. Really chuffed with these.

Received them yesterday, clear night sky, first sighting of M31 Andromeda Galaxy - Great! Really pleased with these binos, they provide long eye relief (I read somewhere 18mm) which surprised me, given that they have powerful 15x magnification. I guess it's helped by the large 70mm objective lens. The image is very good, no doubt down to the BAK-4 porro prisms and multi-coated lens. They focus well, and keep focus (left and right) when moving from distant to near objects (and back again). I am pleasantly surprised how easy they are too handle, despite their size, they can be kept as steady as a pair of 10 x 50s that I tested (but returned due to poor eye relief). I suspect that this is mainly because one tends to hold them by the narrow part of the barrels, as opposed to the main body (prism chamber). Adopting this method means that the weight of those long barrels is better distributed and less likely to wobble. However one must be very careful not to bump those long barrels, else the optics might be significantly effected. A plastic mount is supplied to attach to a tripod, but I bought a more substantial Opticron L mount to use with a monopod or tripod when I want to some support. A more relaxed and comfortable viewing position, which causes less neck strain is to lay on a reclining garden chair. The binos are excellent for the night sky, far better than the 10 x 50 Olympus binos that I tried out. I would highly recommend their use, especially as they enable you to quickly navigate the night sky in a way that is not viable using a cumbersome telescope. Having said that, I will occasionally haul out my telescope to look at some objects in more detail. I think these binos offer the best value for money and ease of use, say compared to the 20 x 80mm binos by Celestron; those are twice the cost, look rather cumbersome, and probably difficult to keep steady (although more sturdy due to its central strengthening bar). The package would benefit from a few inexpensive improvements: 1. More substantial neck strap, 2. More substantial case, 3. Better lens caps on the large objective lens. The lens caps seem to be soft [silicone?] rubber which can press upon the objective lens and they exude a horrible oily substance that is truely aweful to remove from the lens. The single 'cyclops' lens hood that fits over the eye piece fits if the eye cups are folded down (for spectacle wearers), otherwise it is too loose a fit. To get the best use of the binos for the night sky, purchase the Planishere by Philip's, also available on Amazon.

Me encanta Celestron! Cómo podrán ver, tengo algunos artículos 25*100, 25*70 y 20*80 La referencia a este comentario es en base a los binoculares 25*100 es un artículo ya profesional no es para principiantes es muy pesado para maniobra por lo que se necesita de un buen tripié Tiene mucho más profundidad que los otros binoculares que tengo, y mucha más definición... El precio estaba bastante accesible y la compra a meses sin intereses fue lo que terminó a animarme Los recomiendo mucho si les gusta la astronomia

I bought this for around ₹8,000 with card offers, the best ₹8K I’ve spent so far. This binocular is excellent for sky and stargazing. If your budget is around ₹10,000 and you’re looking for a powerful astronomy binocular, go for this without a second thought. The lens quality is very good, and the overall build feels solid and well-engineered. What I was able to see through this binocular: - Full Moon – The Moon does not fully occupy the lens; it covers roughly 60–70% of the field of view, which gives great perspective and clarity. - Jupiter and its 4 moons – Clearly visible on a good night. - A few star clusters – Bright and beautiful. - Orion’s Belt – You cannot see all three stars at once; they can only be viewed separately, which gives a good idea of the high zoom level. Important Note: This binocular is heavy, so a strong and sturdy tripod is mandatory (don’t go for cheap ones). If you want to capture photos through the binoculars, a phone mount is also recommended. I still remember the night I pointed this binocular at the sky and saw a star cluster for the first time, it was truly magical. If you are a space enthusiast, this is an absolute must-buy. Highly recommended!

Si ya tienes un telescopio y buscas una herramienta que te permita tener mayor campo y la flexibilidad de poder tener una sesión de observación in promptu, vas a amar estos binoculares. Bien empaquetados y protegidos llegaron a mi puerta en solo 16 horas. Excelente colimación, buen funcionamiento mecánico (ningún detalle), buena óptica (el recubrimiento casi no refleja luz) y accesorios decentes (la bolsa y el adaptador funcionan; el strap para colgarlos parece broma). Representan un excelente valor dado el precio durante la más reciente promoción (de hecho más barato que en USA). Al recibirlos, en los primeros 10 minutos de prueba pude observar las Pleyades, las Hyades, El cúmulo doble en Perseo y para mi sorpresa M31, con una extensión ligeramente mayor que en mi pequeño reflector de 4.5". Todo desde mi jardín en medio de la ciudad. El enfoque es preciso, el relieve ocular suficiente y cómodo, la aberración cromática es prácticamente inexistente con la posición ocular adecuada y dentro del 85-90% del campo de visión. A pesar de que no tengo mucho interés por la observación lunar, estos binoculares me están haciendo cambiar de opinión con su efecto casi tridimensional. Son pesados y grandes. Para una sesión de observación casual puedes sostenerlos en tus manos unos pocos minutos. Si quieres estudiar los objetos en turno, necesitas un buen soporte. O bien un tripié fotográfico de buena calidad, sólido y que puedas subir hasta la altura de tus ojos, o un monopié para observar sentado. En mi caso lo he solucionado con una excelente base de micrófono para estudio y un adaptador bastante robusto que carga 3 kg. Muy recomendables. Si los ves a buen precio no lo pienses, no te vas a arrepentir.

For what ever reason I was delivered a used product with scratches, burred misaligned screws and missing parts! Contacted seller but no response( was saturday..responded on monday, the day replacement was already on the way). Return was swift and replacement arrived 2 days later. It was proper new one this time! These 25x100s are very sturdy good quality binos. Mine were in perfect focus as far as I can tell and collimated properly. The tripod attachment has a smaller screw size (1/4" instead of 3/8"). Screw has to be tightened very tight, afraid of damaging aluminum threads. I bought a ballhead boasting 31lbs capacity for the binos. It was supposed to have enuf capacity to hold the binos even tilted as it weighs roughly 9lbs. Yeah..really didn't. Wobbly and shake. Setup had a telescope tripod so definitely not lacking there. Ended up going all in with Oberwerk tripod. Perfect choice for the binos. With that setup I can easily look all over with steady view. I'm impressed with image quality and light gathering ability. There's a little bit of chromatic aberration visible looking at moon (clear green hue on light side). Stars (what ever visible from backyeard) look beautiful crisp light spots, chromatic aberration not noticeable. Why point out the tripod in review? These are totally useless by hand. I'm a big guy and can't hold these steady at all, magnification (*25) and weight make it literally impossible to enjoy the view. Sturdy support just is mandatory expense! You cannot avoid it. And preferably with adjustable center column, viewing towards zenith (if standing) requires at least eye level height (6"6' in my case). Else you'll just strain your neck or back ;) Along with binos comes a convenient carry case. Feels robust and good quality to me. Also there is no focus ring on this beast. If you need to focus, you focus each eye separately. Inconvenient if you have several viewers but awesome as you can ditch eyeglasses and still get perfect focus.

En mi caso compré los 12x60. El empaquetado es correcto, proporciona una protección suficiente, dentro todo está bien ajustado con ayuda de foam y entre los tubos objetivos también dispone de un bloque de foam que evita que se flexionen o lleguen a partir en un caso extremo. Llegaron en perfecto estado, tanto es así que no han tenido desajuste alguno en los prismas que requiera colimación, por tanto la visión que proporcionan es perfectamente nítida y no presentan visión doble. Trae con ellos una bolsa de transporte muy básica, cierra con velcro y sirve para poco más que resguardarlos del polvo, también un pequeño paño suave típico de óptica para limpiar las lentes y una correa de cuello que es de risa, no parece que se rompa con la mirada, le he hecho por curiosidad algunas pruebas de tensión y aguanta bien, pero sí es muy estrecha dando la sensación de que va a molestar en la zona del cuello si los llevas un buen rato colgando, así que yo recomendaría añadir a la compra como mínimo una correa más decente. En contraposición a esos añadidos muy apretaditos en presupuesto tenemos que la calidad de construcción de los prismáticos en sí es muy buena, los materiales se ven muy decentes y son bonitos, la rueda de enfoque no presenta holgura y es lo suficientemente dura en su recorrido como para no moverla accidentalmente, las gomas de los oculares se pueden retraer para hacer fotos y se pueden usar con gafas ya que contamos con una distancia ocular de 17mm (quizá sea apropiado retraer también las gomas oculares para ello), adicionalmente y no obstante puedes ajustar las dioptrías del ocular derecho en un intervalo bastante generoso para ajustarlos a vistas miopes/hipermétropes, los prismas Bak-4 generan en la pupila de salida una imagen completamente circular y nítida dando fe de su calidad y cuentan con resistencia al agua, pero NO son impermeables no confundir los términos. Son completamente usables a pulso, pero tengo dos cosas que puntualizar: 1- Peso de 1,1 kg aproximadamente, diría que entramos en la frontera donde a algunos le pueden parecer pesados y a otros no...No sabría decir, de momento no he hecho un uso prolongado, pero sí que he percibido eso aunque yo en lo personal no los noto. 2- Lo mismo se aplica para los aumentos, 12x ya es lo suficientemente sensible como para que quien tiene el pulso que es «incapaz de robar panderetas» sufra en ciertos escenarios por que la imagen tiemble, sea como sea donde más se va a notar esa falta de pulso es mirando a las estrellas y planetas, al menos esa ha sido mi percepción, en terrestre quizá yendo al detalle. Dada la situación en la que se encuentran estos prismáticos entre ambos mundos, terrestre y celeste, estos dos puntos son muy personales, en mi caso no suponen un problema por lo que he probado, pero a lo mejor a ti sí te lo suponen y debes considerar la compra de un tripode posteriormente para uno u otro escenario, si es algo que puedas considerar tu problema estaría solucionado. ¿Qué se ve? Lo único que he comprobado hasta ahora en un ambiente con bastante contaminación lumínica es Júpiter y puedo decir que, con la vista habituada a la oscuridad al menos un poco, se distinguen los satélites galileanos sin problema por ejemplo, más allá de eso dicen que a Saturno lo puedes distinguir con una forma claramente ovalada, pero en mi caso en el momento en que me puse a mirar un poco estaba ubicado en un lugar que desde mi casa es difícilmente alcanzable y preferí esperar a otro momento. Teniendo eso como referencia no dudo que se podrán ver algunas nebulosas, cúmulos, a M31 (Andrómeda) y que la Luna se podrá observar muy bien. En cuanto a observación terrestre son muy satisfactorios, te permiten distinguir detalles a bastante distancia, de ese modo puedes ver como trabajan otros desde una valla con tus pipas a varios km de distancia; en cualquiera de los dos casos su amplia apertura en las lentes objetivo así como su gran diámetro de pupila de 5mm proporcionan una visión muy luminosa, clara y no presentan aberraciones muy marcadas o molestas. Como punto negativo decir que el capuchón protector grande de los oculares se cae solo en ciertas posiciones, así que es altamente recomendable pasar la correa que le pongas por una abertura que tiene para mantenerlo amarrado y que no se pierda. En definitiva yo creo que como prismáticos para aficionados estos representan el punto polivalente ideal para quienes quieran uso astronómico y terrestre, ya que para uso terrestre se comportan muy bien, puedes verle las espinillas a un gorrión y para un uso astronómico te van a dejar satisfecho. Sin embargo si te vas a inclinar claramente al uso astronómico pero no quieres un telescopio yo consideraría unos prismáticos con más apertura y aumento sin ninguna duda.
