Both binoculars excel and have a clear crisp view. The optics are truly amazing at this price point! I did have to send back a set of the 25x70's due to interior dust being seen as I looked through them, but Amazon sent me a new pair no problem. Both binoculars use the same body. The 25x70's are a touch shorter (1/4 inch) in length due to shortening of the Ocular (eye) to the Objective lens distance. The 25x70's also have a larger Ocular lens due to the increased magnification. Both binoculars need a tripod (especially the 25x70's which are more effected by shaking). GET A 70" or greater TRIPOD! I have a 60" tripod and I'm a short5'5" but when something is near 90 degrees over your head the "60 height of the tripod won't cut it.
I posted an example of the magnification and the Field of View difference between the 15x70 (1st Pic) and the 25x70 (2nd Pic). As you can see the 25x70 gives you a greater MAGNIFICATION but the trade off is the FIELD OF VIEW which is greater with the 15x70's. The actual views through the bino's are sharper as the cellphone doesn't do it justice.
LOOKING AT OBJECTS: In looking a celestial objects the MOON totally fills the frame with the 25x70's. The 4 Galilean moons of JUPITER (yes you can seem) look great in both set of binos. Another thing I love to look at are AIRPLANES. With the use of a tripod I was able to see and follow JETS at 35,000 ft. IT IS A MARVEL! The 25x70's work well here as I can read the writing on the planes.
MY RECOMMENDATION: I would choose the 25x70's. The 25x70's are $3 more so why not go for more magnification. The wider field of view on the 15x70's does allow a better "hand-held" experience but you are still going to need a tripod for celestial viewing no matter which bino's you buy.
ALSO: Both the 25x70 and the 15x70 come with a tripod adapter but I'd upgrade to a METAL one as these binos are heavy. The Barska adapter is metal with a larger rubber tightening screw and is only $8 (see photo). I'd also get some Field Optics Research Binocular EyeShields ($14) to help keep out peripheral light in daytime viewing (see photo).
So as my research progressed, specifically in the direction of binoculars, I came across this Celestron SkyMaster 25 x 70mm binoculars. Touted as appropriate for both celestial and terrestrial viewing, especially given the less-than-$100 price tag, the binoculars seemed to me to be a good fit: not a huge investment and would also be a significant step up from my current binoculars. And the price was about 1/3rd that of the 25 x 100mm while still, in my opinion, providing a decent long-distance viewing experience.
I've had these binoculars for about a month now and I have to say that I really do enjoy them.
I should note that I ordered and use the "Barska Binocular Tripod Adapter" instead of the one that came with the binoculars. (Other reviewers recommended this upgrade due to the Barska seemingly being a bit sturdier than the one that came with the binoculars.)
In any event, I already had a modest tripod that is working well enough for me, although the little, almost imperceptible shake that occurs is quite obvious when looking at airplanes, satellites and other celestial objects. Still, I'm not disappointed with my setup.
Now, with these binoculars I can see Jupiter, and at least two of her moons, Saturn, including the "ring," and, of course, many stars. In fact, aiming the binoculars in an area that seems void of stars when viewed with the naked eye reveals even more stars and whatnot. And the view of the moon is spectacular.
Passing airplanes stand out with these binoculars. And while I've yet to actually read lettering on planes (they're usually at an altitude of 35,000-plus feet, moving at 500MPH or so, and miles downrange), I can clearly detect planes' colorations, engines, winglets, etc. What fun!
For terrestrial viewing, again these binoculars provide me a good look.
The only thing I could say that would be even remotely critical would be this: trying to accurately aim the binoculars without the aid of a "finding scope," especially at very distant objects, is challenging. Some times I actually get it right, but most times not. This is especially true of fast-moving objects (satellites, planes, etc.) But this isn't a "problem" with the binoculars, but rather one aspect to consider when using/purchasing such high-powered binoculars.
Overall I'm very pleased with this purchase. I find the binoculars came usable and in great shape right out of the box.

The first thing I would point out is that the 25 x magnification magnifies the slightest movement, so if you intend using them for astronomy for more than a couple of minutes you'll really need to mount them to a tripod. I've been using my camera tripod, and it's more than adequate
A tripod adaptor is included, it's plastic and reasonably sturdy, but for a more stable image it's worth buying a metal one, I bought a good solid one on here for £6 and it's much better.
I've been using the binoculars most evenings this week, Jupiter and its four main moons and Saturn and its rings are clearly visible through them. OK, they're binoculars, not the Hubble, and the aforementioned planets are only very small in the field of vision, but you can see them nonetheless. I think I was able to make out the stripes across Jupiter on a really clear night last week, but that may just have been wishful thinking on my part.
Naturally they can't match the image I obtain from my 4 "refractor telescope either, but they're much easier to set up and use and ideal for short viewing sessions when lugging out the telescope would be just too much hassle.
They're pretty good for terrestrial viewing too, but bear in mind the closest focusing distance is 75ft, ideal for planes overhead and ships at sea, but not for birds at the bottom of your garden unless your garden is 75ft long or more.
I like the look and feel of these binoculars, and I'm very pleased I bought them.
I shouldn't have bothered - very disappointed with them and even with a tripod it is not easy to focus as there is still some shake, just putting your eyes to the lenses. I see far more using the Olympus binoculars.
A mistake, just proving that even at my advancing years, we can still live and learn! Should have stuck with what I had.
My 71 year old dad enjoyed this with his eyeglass, no problem there. The extended rubber eye piece is made for that purpose, to view with eyeglass. Yes it little heavy but hey working out while enjoying scenery is extra benefit. My old dad can do it, there no question you cannot not. During the trek, my dad was the one who was holding it anyway. I was with my Camera and Drone. Man, my dad love this, when he lost it, he was very sad. So I thought I surprise him with gift.
Don't worry about power Adjustment, it's very simple to adjust for all eye level.
I believe Yeti took my last one :D
The day they arrived, the previous few days of clear skies ended with total cloud cover and rain, but the following night I was able to take a look at Jupiter and see the four main moons, as clearly as hoped for. There was a near full moon and I was able to see the full disc of the moon filling my eyepiece, and some lovely views of craters especially along the terminator, then a look upwards to the stars, seeing hundreds of previously invisible stars.
The view is just as good as expected, and although the binos are light, its almost impossible to hold them steady, especially for looking at planets, and a tripod is definitely necessary. I used the included binocular mount to attach them to my camera tripod, its a decent tripod, which I weighted down, but I still got wobble from the lightest of touch when aiming and focusing. I am now looking for a stronger/heavier tripod.
The included case (no padding or zip), neck strap, and lens cloth are poor quality, presumably to keep the price down, I have replaced all with better stuff so I can look after the binos properly.
The front lens caps are ok, but the rear lens cap isnt fit for purpose, its a single cap covering both lenses and does not stay in place, for now Im using the nasty neck strap that came with the binos, tied on to hold the rear lens cap in place, until I find a better lens cap(s).
To sum up, the binoculars are excellent, the included extras are rubbish, but I think I got value for money.
For the price you pay this is still good value for money. Pleased overall.
For this price these are a bargain. Quality build and great magnification. I use them for views across the harbour, not astronomy.
The only slight negative is the halo effect around some objects (a rainbow outline). Apparently this is reduced in expensive binoculars, but for casual use and at this bargain price it is completely acceptable.
ALL I CAN SAY IS WOW!!! IF YOUR PUT OFF BY A HIGHER MAGNIFICATION? THEN DONT BE? THESE ARE AMAZING!! LIGHT ENOUGH FOR QUICK OBSERVATION BUT YOU WILL NEED A TRIPOD FOR LONG OBSERVATION LIKE LOOKING AT THE AWESOME NIGHT SKY OR JUPITER!
PLUS THEY COME AT A FRACTION OF THE PRICE OF LESS POWERFULL BINOCULARS!
MY FIRST SIGHT WITH THESE WAS LOOKING OUT MY WINDOW AND TO MY SURPRISE I COULD SEE A HORSE? I DIDNT EVEN NO THERE WAS A FILED FAR AWAY OUTSIDE MY WINDOW LET ALONE A HORSE?? I COULD NOT SEE THE FIELD WITH MY NAKED EYE? AMAZING! LOL
