Summary: For the price these Aculons are impossible to beat. They are not waterproof but I doubt I'll need them for astronomy in the rain anyway! Visually these Nikons are very crisp and bright and a huge step up from department store varieties. Well done Nikon!
Summary: I just got these binoculars and am having some difficulty turning the diopter ring. At first it wouldn't move at all, but with some persistence and using two hands (4 fingers) I was able to get it to move. I guarantee you my grip is stronger than most. I have been working it back and forth for several minutes and it seems to be getting easier, but still far from easy. Hate to go through the hassle of returning it, but had much higher expectations of Nikon quality.
Summary: I didn't know what I was getting for such a low price, but I have to say that these are Awesome. I am so glad I purchased these. I am amazed at the clairity of this item. I love them and I know you will too.
Summary: These are quality binoculars they're great , magnification just right , any more then images would be blurred. Comes with case and instruction Nikon lives up to it's name. Do shop around though as I did.
