## 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.

### ⭐⭐⭐⭐⭐ Stunning and well worth the money!!
*by K***N on November 5, 2022*

I bought the 25x100... You'll see a lot of people on here who are more than amateur hobby astronomers. If they criticize these binoculars... DON'T LISTEN TO THEM. Pro's should stick to fancier equipment. However, for us hobbyists, this thing is AMAZING!! First, I thought it was used or opened, because the tape on the box was open, but it wasn't, it was all snug inside. It's huge, and heavy. The pics show the 25x100, next to my 2yr old 20x80's (also excellent!) This puppy is way bigger! The views you get are better, closer, clearer. I attached my Galaxy S22 Ultra to the binoculars and zoomed way into the moon, and took pics of Jupiter and his Galilean moons, beautiful... You can see deeper space, as well. For the first time, I had better views of Saturn, still small, but a little better then the 20x80's. The focus is easier than the 20x80, you adjust each eye lens individually, I like that better. The only negative for me, is, the big lens covers aren't attached to these binoculars, like the 20x80's are, so you can possibly lose them. Otherwise, this is an amazing piece of equipment. The bag: I don't understand why nobody ever gives much info on the bag... it's important. They could've done better with it, for the price you pay, but, it gets the job done. The binoculars are in a padding that wraps around the binoculars and Velcros shut, then you insert that in the bag. It seems safe enough. What people don't usually say, is that not only can you carry it with the shoulder strap, but, you can take the shoulder strap off and pass it through the plastic hoops on the back of the bag, and carry these heavy binoculars as a back pack! I LOVE that! It's much better than carrying them over the shoulder, especially for us smaller people. There is also a small zipper pouch on the front of the bag, where I personally store my green laser light, that I use while stargazing. All in all, these binoculars are a wonderful way to exercise your astronomy and deep space hobby!!
