Dear Steven, Could it be that the horizon (below the cross hairs) is too small to resolve as per the hull on it?

Further, why is the following true: 1. Observe with weak binoculars (5x) a ship disappearing until the hull is out of site 2. Take a powerful landscape telescope (100x) and you'll see the hull is straight back in view again. 3. If the powerful telescope is mercury leveled, and it has cross-hairs etched in the centre then why do we not see the horizon below the cross-hairs? The reality is, it's above! Proving the convexity of the Earth is going to be much harder than this, please try again all of you, I'm very interested. Best Wishes, Steven.
