    Stunning and well worth the money!!
    I bought the 25x100...You'll see a lot of people on here who are more than amateur hobby astronomers. If they criticize these binoculars... DON'T LISTEN TO THEM. Pro's should stick to fancier equipment.However, for us hobbyists, this thing is AMAZING!!First, I thought it was used or opened, because the tape on the box was open, but it wasn't, it was all snug inside.It's huge, and heavy. The pics show the 25x100, next to my 2yr old 20x80's (also excellent!)This puppy is way bigger! The views you get are better, closer, clearer. I attached my Galaxy S22 Ultra to the binoculars and zoomed way into the moon, and took pics of Jupiter and his Galilean moons, beautiful...You can see deeper space, as well.For the first time, I had better views of Saturn, still small, but a little better then the 20x80's. The focus is easier than the 20x80, you adjust each eye lens individually, I like that better. The only negative for me, is, the big lens covers aren't attached to these binoculars, like the 20x80's are, so you can possibly lose them.Otherwise, this is an amazing piece of equipment.The bag: I don't understand why nobody ever gives much info on the bag... it's important. They could've done better with it, for the price you pay, but, it gets the job done.The binoculars are in a padding that wraps around the binoculars and Velcros shut, then you insert that in the bag. It seems safe enough. What people don't usually say, is that not only can you carry it with the shoulder strap, but, you can take the shoulder strap off and pass it through the plastic hoops on the back of the bag, and carry these heavy binoculars as a back pack! I LOVE that! It's much better than carrying them over the shoulder, especially for us smaller people. There is also a small zipper pouch on the front of the bag, where I personally store my green laser light, that I use while stargazing.All in all, these binoculars are a wonderful way to exercise your astronomy and deep space hobby!!

    Me encanta Celestron! Cómo podrán ver, tengo algunos artículos 25*100, 25*70 y 20*80

    La referencia a este comentario es en base a los binoculares 25*100 es un artículo ya profesional no es para principiantes es muy pesado para maniobra por lo que se necesita de un buen tripié
    Tiene mucho más profundidad que los otros binoculares que tengo, y mucha más definición... El precio estaba bastante accesible y la compra a meses sin intereses fue lo que terminó a animarme
    Los recomiendo mucho si les gusta la astronomia
