71008 SkyMaster 25x70mm 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)

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

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.

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.

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.
