I bought it for astronomy, birdwatching at the backyard, airplane watching. It provides very clear and contrast picture of astronomical objects, much better than my decades old binoculars. Very good eye shades, good ergonomics and acceptable weight.
Pros: Sharp bright picture, wide view angle, waterproof
Cons: Inconvinient lens covers
