What Can I Expect to See With a 100mm Binocular?

Here’s an example of what you can expect to see with the Oberwerk 25/40x100mm binoculars. This is a view of downtown Dayton from approximately 2 miles to the south. We used an iPhone 4, and simply held it to one of the 25x eyepieces, and again to one of the 40x eyepieces. Click the pictures below to make them larger.
