15-30X80 Zoom Astronomy Binoculars with Built-in Tripod Mount Giant Binoculars with Phone Adapter and Case for Bird Watching Hunting and Stargazing

They are big, bulky, and very heavy. You need a tripod for sure. But they are priced right. Worth the money.

Considering the price, the binoculars work well and yield a clear, sharp view especially at lower magnifications. There are a few limitations, of course, that go along with any high-magnification optics. One is the minimum focusing distance, which I am aware of from camera lenses, but which casual binocular users may not. In other words, don't expect to be able to focus on something nearby, say within 50 feet or so. Another is the use of the binoculars with eyeglasses. The eyecups are rather stiff and instead of folding them down, users may be better off taking off their glasses, if possible, and simply using the magnification of the binoculars to compensate. The third is the necessity of using a stable tripod, particularly at higher magnifications. In addition, the tripod adapter is plastic and, although it seems sturdy, it does have some give to it. So be prepared to give the binoculars a few seconds to cease moving, and try not touch them after they have done so. Again, these things apply to any high-power binoculars, and the only way to avoid some of them would be to add stabilization which would increase the price by a substantial amount.

Until now the binoculars work very well. Are a little more heavy than I expected. They have a great view clarity at 13 - 70. When you up the view at 20 -70 or more, begun to seeing blur. Maybe is for the magnification of the view. In general they work good and I happy gor the purchase.

Garbage product. I was hoping to be surprised with such a low price point…,nope! Could not get the right and left side to match the others clarity. It was one or the other. Not worth your money or time.

These are big, but they aren't very heavy. The come well packaged in a heavy box and form fit styrofoam. The product includes an accessory attachment (for cell phones and similar), a tripod mount, soft case, rubber lens covers, microfiber cloth, and a neck strap. Frankly this is a bargain. The zoom operation is smooth and easy, but you'll need a tripod. 13X is the low setting, and it works okay for handheld. Much beyond that is very difficult to steady by hand. That's a fact for any high power optic, so it's nice that a tripod mount is included. The quality of the image is not up to the typical DSLR camera with a long lens, or to more expensive binculars. However, it's just fine for surveying your realm or identifying that critter on the south 40. The objective lens to eyepiece ratio is a little small. This takes some practice to get a full field of view. I have to hold it a bit away from my eyes. That also diminished low light capability. I consider these late dawn to early dusk glasses. But again, these are not $1500. Construction is plastic, but they have a soft touch feel and are good in the hand. Recommended.

These binoculars are exceptional. The field of view is excellent. The light gathering capability is very good. The Zoom factor is strong steady, and an accurate representation of its stated power. They are actually fairly light for binoculars of their size. I can spilt double stars with them and the moon's craters and mountain ranges are clearly visible. For under $100 these binoculars are unbelievable.

This visual aid is great for bird watching from further than you can imagine. The clairity of the images fantastic. With the phone lens adapter, it multiples the images XXXX. Star watching is also spectacular. For the price you can't go wrong.

These are very light and easy to hold.

Pour l’observation des baleines

Que la vue est bien nette article de très bonne qualité.

Nice Binoculars but mine came with no instructions. No instructions for the tripod adapter, I had to come back to the pictures her to work this out and a phone adapter that was different to the instructions supplied and rather difficult to use.

Das Fernglas hat durchaus gute Eigenschaften. Für meine Anwendung jedoch zu schwer und zu groß und daher schlecht beim Wandern mitzunehmen. Es ist eher für stationäre Anwendungen gut geeignet.

Für Naturfreunde und Hobbyastronomen ist das Fernglas bestens geeignet .
