Question: I am looking for binoculars for stargazing--I want light-weight 10x50's (see another question, below). If  these are not good what is?
Document: I was looking for something for stargazing. I read a few reviews and bought it. I couldnt see the stars but the binoculars if of excellent quality, the optics are very clear without no color distortion. Its reasonably light weight for the cost and magnification. The material is very good and doesnt feel cheap. If you are looking for a binoculars to take on a field trip, hiking, trekking, sightseeing etc this would be pretty good.
These binoculars perform very well during daytime and are good for the occasional birdwatcher or for viewing any outdoor event. The light weight and the insta-focus make them very easy to use. I bought them for stargazing (very tight budget!) and I am very satisfied with them giving what I paid. I have been able to locate and clearly see many Messier objects (ie.
Great tool for hunting and sports use. Price is right, and the quality is good. Good optics and light weight.
Good wide viewing range and good light collection. Easy to focus and light weight. Can be used for many purposes.

I use these to coach a rowing team from land, so here are some good data points about visibility at various distances. The boat is about 60 feet long and has eight people rowing in it.- Within 50 meters binoculars are not necessary in daylight but in very low light (e.g. at night) they are quite helpful in making out details.- At 50-200 meters away I can see all eight rowers clearly and steadily without having to use the zoom at all.
I was in the market for binoculars primarily because I wanted to go stargazing. I wanted something with a 50mm objective lens because research has told me that a large objective lens allows more light.I chose this product due to the overall great reviews on this product, as well as the price. I can comfortably say that I do not regret buying this binocular, because they really are great. They feel very durable.
We were not impressed with the lens caps, which are pretty loose, but we don't normally use them anyway. These binoculars  are big and not as portable as the 7X35's, but that's understandable for 10X50's. I have looked at the moon and some stars, although I had to to &#34;prop&#34; them to get a steady view. If you plan to carry your binoculars  for long walks, you might want to get something a little smaller, but for us, these are perfect.
I recently purchased these binoculars to take to the Arizona Diamondback's home game. They are light weight and easy to use. I would recommend them to anyone. The only draw back was when we tried to view the stars and the moon, they were very difficult to hold steady. I paid a whopping twenty-five dollars plus shipping and thats alot of Bang for my Buck.
I am a rookie bird-watcher and I would recommend this pair of binoculars for bird-watching/binocular astronomy. It can be used to track birds in flight with comparitive ease, and this is a big plus. The insta-focus is a nice concept, especially in winter when the standard knob that binoculars usually have, is a nuisance. The weight, too, is quite manageable.I found this adequate for most birding, except for things like identifing small birds in dim light.
Answer: These are a great pair of binoculars. Real light for their size. I used it while on safari in Kenya and they are perfect for a long day carry.
