    • Fantastic for anything where you won't have to change focal distance much.
Style: SkyMaster 25x70 Binocular Set: Binocular only
I originally gave these four stars because the focus has play in it. I bumped them up to 5 stars because of the low price and the fantastic astronomical views. They stay in the focus you put them in, but the play occurs only during adjustment. My 16x50 is much better for daytime sight seeing. 1. The eyepiece lens is 23mm, vs 18mm for my Nikon Aculon 16x50, 16mm for my Celestron 10x50, and 13mm for my Tasco 7x35. Despite this, they have the same eye relief as the smaller binoculars, and also a moderately smaller apparent field of view. 2. I followed the exit pupil, drew a triangle, and quickly and accurately measured the apparent field of view of the Celestron 25x70 to be only 57.5 degrees, and that is the maximum no matter where your eye is. My Nikon's are 61 degrees, my Celestron 10x50 is 60 degrees, and my Tascos are 58 degrees. Visual observation confirms these math measurements. 3. They are noticeably heavier than my other binos, but not a lot. 4. They are easy to hand hold very steady in the day time, without resting my elbows on anything. At night it is much better to have something to brace my elbows on. 5. They look like they are good quality, other than the thin strap. 6. They are 10.4 inches long, and 8 inches wide. 7. There depth of focus is less than that of lower powered binoculars, so I really have to adjust them as I aim around at stuff terrestrially at different distances. These are better for astronomy than for birding. My 10x and lower did not need to be adjusted much unless I looked at something really close. My 16x is in between, but still pretty forgiving. 8. The focus is smooth but has a short lag, and requires diopter adjustment of the right eye to compensate for the lag. In cold weather, the focus wheel is tighter than any of my other binos, but still reasonable enough to turn. 9. I am a bit near sighted, so I get a closer near focus at around 50 or 60 feet instead of the advertised 75 ft. My nikons near focus at 18 ft, not their advertised 28 ft. As many other reviewers already said, the eyepiece barrels seem too big around, and pinch my nose if I try to get closer to the eyepiece. However, if I carefully measure the interpupilary distance, I can place them so I see the full field of view without the pinch. It just does not come as naturally as with my 10x50. I separated them to see if getting one eye closer would give a bigger field of view, but it did not. I guess how close I get is close enough. It just feels weird them being that far out on my nose and making that third point of contact like that. Edit: next day: I'm getting used to the new feeling. The correct place to hold these binoculars is by the barrels in front of the prisms. That is how to get steadier views. Better yet, slouch down in a chair and put your elbows on the arm rests. Then all you'll see is your heart beat. I looked at a distant light, and compared its size to the Nikon's 16x. I find it very believable the Celestrons are 25x. The field of view is not as wide as advertised. The apparent field of view is 57.4 degrees, not 61. The belt of Orion just barely fits in the view. The moon is 30% of the view. The true field of view is 2.4 degrees, not the advertised 2.7 degrees. The arms of the eyepiece adjuster also have some wiggle in them causing a 1/4 inch delay when turning the adjuster wheel. I have had to re-adjust the right diopter even when I did not touch the center wheel, indicating it might be moving a bit. But it does not take long to get back into focus. There is also a flare visible off to the side of the exit pupil, though I don't see it during astronomy. Despite these flaws, I can't subtract a star at only $70 shipped. These binoculars are a league above my 10x50 for astronomical viewing, at least in terms of looking at individual targets. A telescope has many advantages, but these are grab and go. However, to see the phase of Venus, you need to stop down the aperture and sit down to brace your view. ------------------------- I easily saw the correct shape of the Orion nebula on a half moon when my 10x50 could see nothing. I could see the dark side of the half moon, whereas my 10x50 could only see the bright side. My 16x50 also saw the dark side. Jupiter looks much bigger in the 25x70, but I may need to reduce the aperture to see the stripes. I can see bands on Jupiter 114mm f8 Newtonian telescope at 28x, but I can't see bands at 25x in the binoculars. The Pleiades look much better in the 25x70 than in the telescope or my other binoculars. The double cluster in Perseus is clearly visible in the 25x70, and looks tiny with an almost stellar core in my 10x50. Andromeda, M31, looks better, with M32 and M110 noticeable by it, and very hard to see in my 10x50. I can see a tiny ring around Saturn at 28x in my telescope, but at 25x, I sometimes see a ring around Saturn and sometimes I don't. On the day that I could see a ring, my 16x50 detected ears. I can see M13 and other globular clusters as small fuzzy balls. I could find them in my 16x, but smaller. In my 10x, I can locate most of them, but they look like stars. Maybe I can detect a little fuzz on M13. In my 7x, I can't locate most of them, but I can see M13 and maybe a few others, though I don't remember. All of my observing was hand held, unbraced. I could point them at whatever I wanted and hit my targets just fine. I had trouble hitting Andromeda right away because I could not see it naked eye. M82 and M81 are easy to identify in my 25x70 as I sweep over them. I can see the cigar shape of M82 in my 16x50 too, though I can't find either one in my 10x50. I can see a mountain range on the moon in the 25x70 when my elbows are braced. I've not yet found it in my 16x50. Airplanes look bigger but take longer to find in my 25x70. At 25x, you can't tell where you are in the sky from the star orientations. You just have to point and look, and you know where you are when you see the object you are looking for. At 16x, I can pan around from bright star to bright star and figure out where I am by memory. At 10x, I can see some bright stars in the same field of view, but have to pan for others. And at 7x, you can easily see where you are. I actually think my view of M31 was more enjoyable in a 15x70 than in these 25x70, though I know the Orion nebula is better at 25x. It keeps getter better even at 60x. M33 can be located at lower power, but the 25x70 gave the best view, giving maybe a hint of spiral structure. ... show more

Magnification and clarity are good for this price point. The attached pictures were all taken with a Samsung Galaxy S21 with the binoculars mounted on a tripod. The photos are in order of increasing distance. All photos are using some level of zoom on the camera. The house is ~3 miles away. The large antenna is ~7 miles away, and the antenna is ~100 ft tall. The "small" antenna is ~30 miles away. The blue and green artifacts on the moon are mostly from the camera. I tried with an iPhone too, and it took better pictures of the moon. The last picture is of Jupiter and its moons. I couldn't get very good definition of Jupiter and it looked mostly just like a large white dot, but I didn't really fuss with it either. Everything looks better through the binoculars than the photos represent. These binoculars work best when mounted on a tripod. Overall, I recommend them. ... show more

    • Poor neck strap included
Style: SkyMaster 25x70 Binocular Set: Binocular only
I love these binoculars. I can see really far and fairly clear. you need to use a tripod to keep the shaking down or sit in a chair and rest elbows on arms of the chair or elbows on a outside table to steady the binoculars. The only reason I gave this a 4 star is because of the very POOR neck strap which is about a quarter inch narrow and still don't know how to attach them to the binoculars. Haven't found a video on how to do that. I like to have a decent strap around my neck just in case I trip or slip and loose my hold on the binoculars, the strap will catch stop them from falling. Unfortunately that quarter inch wide strap isn't comfortable and really cuts into ones neck. Why such a nice binocular and such a lousy strap? ... show more

    • I am very pleased!
Style: SkyMaster 25x70 Binocular Set: w/ basic smartphone adapter
These stargazing binoculars are fantastic! So far, I've only seen the Orion nebula. I had to buy a tripod which wasn't that expensive on Amazon and was very well built. To look at small points of light at night and shake even the slightest bit while holding the binoculars, makes it impossible to enjoy. They're heavy but they're very strong and they are well built. The ride nebula was not as big in The view as a telescope would have been but you can still see detail in the beauty of God's creation. I'm looking forward to setting up the tripod and viewing even more of the evening sky. ... show more

    • Tripod/Monopod adaptor
Style: SkyMaster 25x70 Binocular Set: Binocular only
The adaptor that ships with the unit does not work with any monopod or tripod. The adaptor that does work is part number 93524. When I called it to Celestron's attention, they shipped me the part free. I am using a monopod (as opposed to a tripod) with the binoculars.
