I use this scope primarily for birdwatching. It has a great, bright image at 20x, and very good image at 60x. The resolution is nice - I could see the tiny whiskers on a Brown Thrasher in my backyard with it. I've tried it for astronomy also, and its very useable. I could resolve the rings of saturn with it, and even barely make out titan, one of saturn's moons. I've looked through better scopes, but not at this price point. I'm very pleased with it.
Pros: ED glass, nice zoom
Cons: none so far
