Bakester, two main reasons. One, SC's video isn't quite as sharp as it could be. Maybe he was a tad out of focus or some of the clarity was lost in the transfer to Youtube. You can tell this because the data displayed in the data bar at the bottom isn't crisp like it would be when viewing directly with the eye. Also, that is the nature of the lower resolution, micron distance, and a tiny lens. The images looks a lot like my old FLIR PS32 handheld image.
