>I think an obvious Fisheye type of lens = a Zoom lens This is literal retardation. > Curvature makes the end of the bridge (far away) almost 500 m lower More retardation- and this would make the trees WAY over the horizon. A point high enough to do this would have to be higher than the amount hidden over the horizon due to curvature, which in this case as about 284 ft. The building that was taken from is about 30 fet tall, and even if it was another 50 feet down to the water, the trees would still be over the horizon by 200 feet. >I do not understand that trying to point a laser at someone's eye 24 miles away is an impossible task A Laser Transit is the only way to even attempt this, and even then trying to blindly hit a target that far away would be damned near impossible. If you are off even a tiny fraction of a degree in any direction you would not hit the target and thus this test would always yield a negative result. Again, the sad part is that you think you are actually making valid points, when in reality you are announcing that you are retarded.
