Astronomy Binoculars - 20x80 for Adults, Outdoor Waterproof Binoculars for Bird Watching, Travel and Stargazing with Tripod Adapter and Carrying Bag

Well, I worked with the finest cameras all my life, so I did not expect much from these binoculars however, optics in photographic lenses in the past 3 years have gone through a revolution and I thought maybe these binoculars would benefit as part of the overall improvement in lenses. They did and are great for the money without exaggeration. Optically, except for outer field chromatic aberrations, these are as sharp as 2K$ binoculars in the center field with excellent color. At a distance of 200ft. , on cloudy day, 3/16" high lettering on a security tag is razor sharp . I have these on an expensive tripod with a 3" dia. ball head. These binoculars are mechanically perfect, smooth with just right resistance, great fitted case, quality coating on all optics, bright with VG contrast, fitted lens caps that work, excellent engineering and balance , flawless workmanship and great looking with quality materials used throughout. 9.0 rating for this sample I purchased here on Amazon. I purchased these because I could not find any actual reviews about this particular model on line. Very pleased now. Cannot tell how they will take abuse rain and weather however, I do not abuse or drop my lenses ( some cost 4k). I cannot comment on overall quality control of this company since I am not familiar with its products. P.S. the lenses are not bright red as depicted.... light orange red . Just looked at full moon and craters on edge are amazing like mountains in 3D.

I'm not an expert, but I'm very happy with the visual quality these binoculars have. Granted, I don't have another pair to compare them too, but they seem to be very sharp and the image is very bright. The eye relief works well for me too and I'm a 68 yo who wears glasses (I use the binoculars without the glasses). Do note that these are NOT light. I use them in conjunction with a tripod. That stabilizes the binoculars and makes for enjoyable viewing. All in all I'm very pleased with my purchase and I wouldn't hesitate to buy these again, should the need ever arise.

I'm not impressed with these binoculars. I'm way past that. They blew me away!My first look through these binoculars was a few minutes ago after the delivery. Looked out at some distant trees and could see bees flying around a hive. Crystal clear images.I bought these for watching aquatic life and a few celestial objects because the price was right.These are light and easy to carry in one hand.They feel well built and seem to perform as well as my old Celestron 80mm×20 astronomy binoculars. Those were very heavy but I liked them.I'd even recommend these binoculars for kids.

Love these but they are heavy! You’ll need the stand for any serious bird watching.

Binocs arrived in excellent condition, over wrapped in a bag, nestled inside a foam carrier and fitted inside a heavy cardboard box. The binocs looked very clean and lenses nice and clear. All lens covers fitted tightly. The package came with a tripod mount that worked as intended. They included a smartphone camera adapter as a bonus.I'm amazed I could buy these for about $45 out the door! 15x70 is a powerful size to weight ratio for serious viewing. Tripod this unit and see a new world of detail. 70 mm objectives allow a lot of light for bright images. Ever wonder what detail a hawk can see? These will feel like that! Tailfeather, out.

The media could not be loaded. Después de leer tantas reseñas estaba algo preocupado con el control de calidad de los binoculares 15x70 y 20x80 que ofrecen diferentes marcas. Al final me decidí por este por la relación costo beneficio y la facilidad de importación a Colombia.Tenía un 10x50 y es la primera vez que uso un binocular 15x70 y quedé gratamente impresionado por este modelo de ESSLNB:1. Se nota que el fabricante ha realizado un par de concesiones en cuanto a calidad de construcción para mantener el precio, el prisma usado es Bk7 pero el diámetro del objetivo ayuda a que no se aprecie demasiado la típica viñeta en forma de rombo. Aún así el apartado óptico me pareció favorable, la estructura es metálica recubierta en goma resistente. Dicho esto, no creo que el objetivo de 70mm esté completamente sellado o impermeabilizado por lo que pretendo mantenerlo alejado de las salpicaduras e incluso la elevada humedad del entorno.2. Llegó rápido a mi país y sin problemas de alienación o colimación. Puedo ver estrellas como puntos. Ligera cantidad de aberración en bordes o áreas de alto contraste que parece estar dentro de lo normal. El campo de visión es suficientemente amplio para observar la luna y alcanza a cubrir el cinturón de Orión.3. Buen tamaño, se puede sostener por unos instantes para una verificación rápida de pocos segundos, pero realmente requiere de usar trípode. Incluye un adaptador de trípode de plástico rígido que introduce algo de vibración y puede llegar a fatigar, por lo que sugiero comprar un adaptador metálico para que la visión por el ocular sea más tranquila.También incluyó un adaptador para hacer tomas con el celular. Cuesta algo de paciencia orientar la cámara del celular con el centro óptico del instrumento para ver el circulo de imagen y evitar los bordes negros y apagones. Si el ocular no es cubierto por completo tiende a introducir destellos. El sistema de sujeción al celular es de ventosa y no de tornillo, por lo que asegurarse que logre un buen sello y que puede con el peso de su equipo antes de fijarlo al ocular.4. Dejo muestras de alcance realizadas con el celular. Aún no he realizado la medición correspondiente para verificar si cumple con 15 aumentos.Estaré actualizando mis impresiones conforme pase el tiempo y siga usando el producto.

Way too heavy and not as clear as I hoped for when looking .

Very nice product, great quality
