Binoculars 30X80 Tenjin Astro Astronomy Binoculars with EVA Carrying Case Powerful Binoculars BAK4 Waterproof

These binoculars exceeded my expectations! The picture clarity is outstanding! The focusing is great and simple to use. The magnifications were again outstanding! It's the perfect pair of binocs for stargazing and for the price, you're getting 10 times the quality! The quality of the overall construction and clarity were far better than i expected! For the price you simply can't beat it! I truly have nothing bad to say about them! Besides the weight being slightly too front heavy, it's difficult to keep steady for long using only your arms and shoulders, and they're quite large; which i anticipated for, so I'll give you a tip, i learned that itsomewhat helps to hold them closer to the front lenses where most of weight is, rather than closer to the back or the eyepiece.it helps to steady them for longer using only your arm and shoulder strength. So a very sturdy tripod is recommended for these beauties! Along with a cell phone adapter to record video and take photos along with the zoom of your camera you can zoom in even further to enhance the magnification of the binocs, and once it's focused properly you will be amazed! I highly recommend these over the much more pricy ones which preform equally and some to a lesser degree! 5+ ⭐'s!!

I compared it to a similar very popular brand. This is much better binocular, very little chromatic aberration, super sharp. Came with a durable case. Well worth the money!

Superb! Well packed in boxes (2), then in foamed manuf box. Have smaller nice binoc’s, one mil. These are exceptional performers as those of any price w/ nice durable case, bionic eyes! Waiting for tripod attachment to use tripod. So, that’s what’s up there in the view mountains. Could see Oregon Bigfoot, yet not counting on it.

Good value for occasional terrestrial use. We use it to look at boats out on Lake Michigan, events in the park across from us, and pedestrians or traffic jams. The moon looks nice, as well. Definitely requires a tripod for a stable view. We use the aluminum Celestron tripod (~$100) on a rolling mount (~$50) in our living room on hardwood floor. The binos are on backwards because I haven't ground off the stopper nub on the tripod yet. You have to do that to use it for terrestrial viewing if you want the adjustment controls to be on your side. FYI, the Celestron XYZ phone mount will not work on these binoculars if you have a large format phone.PROS- good value for the price- easier on your eyes than a spotting scope- good enough for occasional useCONS- very light for its size (feels like a cheap toy)- pronounced chromatic aberration (anything white gives off a distracting purple halo)- the knob for tightening the binoculars on the center rod will not get tight enough to prevent it from rocking unless you get them set into position and then use Thread locker- anything outside the very center of the view field gets blurry. We originally purchased a Celestron spotting scope that cost 3x what this does and it did not have any blurring or chromatic aberration even though it had a larger field of view.CONCLUSIONIf we used these more often, I would return them and buy the Celestron 25x100s but for infrequent use they do the job well enough.

A strong pair of binoculars that are perfectly aligned when you get them. No more returning 2 or 3 pairs of binoculars because they are out of alignment and can’t be aligned.Really a great pair of binoculars. The light capture of 80mm primary lens is amazing. This was the best buy I have ever made in a binoculars, I live on lake and I literally owned six other pairs of binoculars. These are now my best pair, by far👍🏻

I know the reviews said these were heavy so I should have known better but they are really heavy. I definitely wouldn't be able to use them without a tripod. I'm a petite person so I can't even focus them without a tripod because it's hard to get my hands to reach the center focus dial and hold them at the same time. I had to purchase a new tripod because my old one (for cameras) would not hold the weight. I was finally able to get it focused on the moon and it was great but still haven't been impressed on viewing the stars. Could just be operator error and needing more practice. I would have returned them if I hadn't waited too late and let the date pass. I also ordered the I-phone adapter for taking photos but haven't been able to figure that out yet. I can't keep it stable enough on the tripod. These probably are decent binoculars but I wouldn't recommend them for a beginner.

More than what I expected Great for nighttime star watching.

Granted, Jupiter is currently at its closest point in 59 years but with just a monopod it was easy to focus these binocs on it well enough to clearly see 4 moons around Jupiter. I took them to Death Valley and in that dark sky I saw a fields of stars so deep it was disorienting. These binoculars are big fellas so don't plan on using them handheld very much. I only used a monopod for quick convenience - really, you need a tripod to do these justice. For people who don't fancy themselves astronomers but just want to see interesting stuff in the sky these will do as well as a lot of popular backyard telescopes, in my experience.
