You are kidding right? So Nikon makes a camera lens that can see through the earth? That’s what is going on when something is below the horizon. You can’t see the object because the earth is literally in between you and the object so unless this camera can see through mountains then it can’t see things below the horizon. If you believe the Earth is flat then you can easily believe the moon is made of cheese. There is equal evidence of both.
Well, there is a small degree of refraction caused by the atmosphere, so you can technically see something that has gone just below the horizon if you can see far enough and the atmospheric conditions are right.
That is the whole point, they can see the objects and they shouldn't be able to. Of course if you refuse to see for yourself I can't make you.
