## Description

Celestron has designed and engineered the largest SkyMaster model to meet the special demands of extended astronomical or terrestrial viewing sessions with its massive 100mm objective lenses and powerful 25x magnification. This extra-large aperture binocular ensures high performance in all weather conditions and is ideal for astronomical viewing, or terrestrial use. Due to its size, weight, and high magnification levels, this binocular should be mounted on a standard photographic tripod for use. We’ve included an integrated tripod adapter rod that allows you to mount your SkyMaster binoculars on any sturdy ¼”-20 photographic tripod in seconds. Astronomers have praised the Celestron SkyMaster for decades for its high-quality BaK-4 prisms and multi-coated optics, which enhance contrast and bring out bright, sharp images—especially in low light conditions. The binocular features soft, comfortable rubber eyecups that block stray light. Eyeglass wearers can fold down the eyecups and view with their eyeglasses on. For maximum stability and secure optical alignment, the 100mm SkyMaster model features enhanced structural reinforcement to the main binocular body. Your purchase of the Celestron SkyMaster 25x100 binoculars includes the built-in tripod adapter, objective lens caps, a rainguard, a deluxe carrying case, a neck strap, a lens cloth, and an instruction manual. Buy with confidence from the world’s No.1 telescope brand and a leading binocular manufacturer, based in California since 1960.

Review: Well worth it. - This thing is way better than telescopes in the same price range. The range and clarity is insane. The only downside is it's weight making the smallest movements with your hands translate to what you're seeing as very shaky and unstable. Laying down or leaning back with your elbows supported can negate the earthquake effects somewhat. I would recommend placing your hands further away from your face while holding the binoculars for more stability. It does have an option for a tripod holder but I've never used it. Another downside is the backpack thing it comes with is poorly made and can barely fit the binoculars. You don't really need it anyway. Just don't lose the rubber lens covers. I dropped it on concrete it's first night but it has virtually no damage. But I've really enjoyed the beauty of the stars through this incredibly well-made, clear, and versatile pair of Stargazing Binoculars. It's worth the price for sure.
Review: Hello stars! 25x100 celestron here - 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.

## Questions & Answers

**Q: I am trying to decide between this model and the Celestron 25-125x80 which i would use at only the lower magnifications. Which should I get?**
A: Hello! In my 50+ years as a user of hundreds of types of lenses, telescopes and binoculars I have found any "ZOOM" product is far less sharp than a fixed millimeter group of lenses. I currently purchased the Celestron 25 X 100 astronomy binoculars and could not be more pleased. Images are all very sharp with excellent contrast - both of which are extremely important when looking at the night sky as well as in terrestrial viewing. I would definitely recommend the 25 X  100 binocs. Hope this helped.   Terry D

**Q: Would I be able to see the rings of Saturn with the binocs?**
A: Just got these in yesterday from another retailer and yes if your steady enough or use tripod you can see saturn's rings. You can see the brightest of jupiters 4 moons as star points too. I also got great views of the Orion Nebula (M42) which was amazing. All objects mention above where seen from the city.

**Q: With this pair not having focus or zoom lever, would the 25-125x80 be a better pair for astronomy searching?**
A: I own the zoom model 25-125×80, and now I wish I had 25 x 100. 

Please DONT BE FOOL BY THE ZOOM FUNCTIONILITY. 25 x 100 will definitely give you crisp image because its prime lens. My zoom bino has some soft-image problem at the edges and it seems to be very common issue. 

Zoom is just useless. 100 aperture will give you more light and 25x is enough to see planets and stars. Again, having individual focus ring is better that you wont get in 25-125x80 model.

**Q: Are these suitable for bird watching?  Specificaly birds of prey?**
A: No, not at all they are like hand holding a celestial telescope. If rested on a car roof they might work, but they are annoyingly large for transport. They require a tripod and good for the viewing of a fixed object like a pack of wolves at Yellowstone 1 mile out. This much power and the binocular view is just too bouncy. The best bird watchers / NASCAR watching for the money I purchased were the Vortex diamondback 8X42. Waterproof and very clear glass, great in low light and not terribly expensive compared to the competition in this performance range. Don't get me wrong as they are a nice addition for sky watching the moon, rings on Saturn...., but practical for bird watching no.

### ⭐⭐⭐⭐⭐ Worth the weight
*by B***N on October 3, 2017*

I purchased the SkyMaster 25x100 Binoculars. They are heavy, and you will need to use a very good tripod to support them. You may need to factor in at least another $100 to the cost of acquisition, and more if you're tall. I suppose you could sit in a lawn chair and use the binoculars with your arms resting on your chest, but even a strong person is going to tire quickly. The view you get through these binoculars is better than one would get from a telescope at the same price point, and the optics gather a lot of light. There is some chromatic aberration near the edges of the lenses, but it is slight, and doesn't interfere with the detail. Astronomical binoculars, like telescopes, require a little practice, patience, and care to provide the best views. These binoculars are easier to set up than a telescope, easier to put in your car and head out into the dark, easier to focus, and easier to look through, but they are still astronomical binoculars. I don't recommend these for most kids, as they are too heavy and require a non-trivial amount of strength to place and secure them on a tripod. I would only purchase these for someone who has an obvious serious interest in amateur astronomy. The other thing that kids, and some adults, do is grab onto the binoculars while viewing, and then complain that they can't see anything. I'm not a parent, and I can only stand about 9 seconds of some kid, or adult for that matter, whining about the view before I start seriously thinking about packing stuff up and going home. Ordinary field binoculars, mounted on a tripod, will provide extremely good views of many celestial objects, are much more kid-friendly, and generally make better gifts. Addendum: I purchased a heavy duty video pan-tilt head for the tripod, and mount the SkyMaster binocs on that. Here is the one I purchased: https://www.amazon.com/gp/product/B0017LEESA The binoculars are MUCH easier to manipulate with the pan head. But the pan head itself is heavy, so make sure your tripod. The Orion heavy duty parallelogram looks like it might be better, but you need to drop another $500 to get that. If you already have a decent tripod, the pan head is about half the price of the parallelogram. I purchased the Manfrotto 229 3D because the reviews from people with heavy equipment were very positive. The SkyMasters are a lot heavier than most consumer-grade high-def video cameras.
