I received these binoculars last week. I purchased them primarily as an astronomy tool, and as such have only used them one time with clear skies. I tried using them the first night I received them even though it was cloudy. I was suprised at the number of stars visible through the clouds when using the binos. The naked eye couldn't see anything. The next night the skies were clear and the views were beautiful. I was very pleased with the views that I received. I own an 8 inch reflector telescope that I have used for the past 6 years. The aggravation of carrying it outside and getting everything setup prevents me from using it often. The ease of grabbing a pair a binos and walking outside for a look around the sky is going to be great. If I stay out for 10 minutes that's okay becuase all 10 minutes will be viewing the sky. With the telescope I can't even get it outside, get the lens caps off, eyepiece installed, and a chair setup it 10 minutes. So anything less than 30 or 45 minutes of viewing time is too little to be worth the effort. Not so with binoculars. The only thing I have to wait for is my eyes to get dark adjusted. And that isn't much of an issue because the 50mm lens give such a bright image I can start looking immediately upon going outside.
For anyone new to astronomy the temptation is always to go for high magnification. Please do not fall for this misconception. The wider angle view and brighter image from lower power is almost always more appealling. It is much easier to find a target and keep it in view as well. This is especially true with hand held binoculars. The 7x magnification of the binos are on the lower end of what is available, so a new comer might be tempted to try a higher power to get a close up view. I almost purchased 10x, but I am now very glad that I did not. It is hard to hold an image still, and the higher the magnification the harder it becomes. I think the 7x is just right.
I took a fishing trip down to the coast this weekend and carried the new binos along. The fishing was good and the views through the binoculars were excellent. They give a very bright, crisp image.
The only drawback to me is that the binoculars are a bit heavy. If you use them for extended periods of viewing expect your arms to become a bit fatigued. However, that can't be used to count against them as it is expected with the large 50mm main lens. Furthermore, they are equipped with a hole for mounting to a tripod, so that is always an option if you need help supporting them.
So far I am very pleased. The Nikon brand was a bit assuring to me that for the price I would get quality optics and they have lived up to the reputation. You can feel confident in purchasing these binoculars.

I purchased these binoculars last winter for stargazing because they seemed to be the best price for what you were getting. Indeed, these 7x50s have helped me see craters on the moon, open clusters, even Jupiter's moons in decent viewing conditions. Light but sturdy, too. I am an absolute beginning amateur, so I can at least recommend them to other beginners.

Clear, bright image. Comfortable eye cups, which can be removed if you wear glasses. I do wear glasses, but my astigmatism is mild, and I am able to adjust the diopter on these binoculars to enable me to use them without my glasses. My only minor complaint is that the lens caps aren't permanently attached to the strap. Instead, they hook on to the strap after you remove them from the lenses. The hook holds them fine, but I plan to use these for sailing, and I suspect it won't be long until I drop one in rough seas while fumbling to hook it on the strap. The eyecup caps don't have this issue, since the strap goes through a loop, and they are attached permanently.
