A phone/ipod with camera. Some cheap binoculars (you can use a scope for a rifle but, I'll be using binoculars).
Step 2: Attaching The Bioniculars
Make sure your camera can see out it. Then if you want you can just hold the binoculars/scope over the camera or you can use some putty for it to stay on.
Step 3: Finishing
Feel free to take pictures of stuff far away now. The two images above are pics of a house across the street. As you can see it works very good. If you have any questions just leave a comment. I'm not responsible for what you do with this. Please mind your manners.
