It was only about 10 yards. I need to work on getting the focus set up better so that the entire field on the phone is captured. I recorded this on my iPhone 5S mounted to a spotting scope, so the only motion you see on the video is from me tapping the start/stop button. Another poster suggested using the volume controls on the earphones to trigger the start/stop. I may need to look into that. It isn't great shooting, but what is impressive to me is that i put together the whole thing right on my phone using iMovie and uploaded it to YouTube from there.
