Input:
This scope has impressive optics, especially for the price. At 20X the view is clear, sharp, and wide. The closer you zoom to 60x the image deteriorates in terms of clarity and color, as do all zooms. I've used this scope for birding and other wildlife and have no embarrassment letting Swarovski or Leica scope owners view through this scope. Got a great first view of an Indigo Bunting at 20X and was able to ID a surf scoter at 60X. For the money, this scope is exceptional. To attach a camera, you only need to pry off the rubber cup on the eyepiece and screw on a T ring for your make of camera. This scope is definitely waterproof. I used it in a steady rain during a birding class trip with no harm to the scope at all, while my cheap binoculars fogged completely.
