Why does an astrolabe not point to the horizon when observed at high altitudes?

At sea level the astrolabe will reveal the horizon to be at zero degrees, but as you increase your altitude the horizon begins to sink below the zero degree mark.  In the FE hypothesis, what causes this to happen?

For an explanation and demonstration of what I'm refering to check out this short video segment:


Not only does he demonstrate the phenomenon, but he also explains how the phenomenon was used to calculate the size of the Earth a millenia ago, down to an accuracy of about two hundred miles.

Of course the Astrolabe (and probablly most any instrument for that matter) is a very troublesome device in the FE hypothesis, here's another refresher course:

In my days away from exertion, ancient devices of navigation have fascinated me. I remember back to one of my extensive conversations with one of my intellectual contacts. We discussed with great vigor the operation and the source of the Astrolabe.
For those who are not familiar with this device, it is a metal disk that was held suspended by a little ring. On the disk was a scale and a ruler near by to measure the information. I was skeptical of this device upon hearing its vile name, in time I will show why it is a device of deception and dishonor.

Why don't you hold your dribble until you can show something? You waste our time. The name of the device has absolutely no bearing on its function or accuracy. Do please stop such unworthy attacks.

Don't tell me, let me guess.  An astrolabe only works if the earth is round.  But since we all know that the earth is flat, then it must obviously be a tool to further the round earth lie.  Does that sound about right?

Fix'd.

The word you're looking for is "drivel" (I only point that out because I've seen this mistake from you a number of times).

You're right. Thanks.

It has been a good deal of time, would you be willing to reveal to us how the device is of "deception and dishonor"... now keep in mind as far as its ability to point to the horizon (at sea level), that is a fairly simple function.  In fact you could use a 3 dollar level bought at wal-mart to acheive the same effect.

What needs to be addressed is not the astrolabe or any instrument, but the horizon itself.  The effect has nothing to do with the astrolabe, and everything to do with the horizon.  I hope that is not too subtle a distinction that it is lost on you.The astrolabe merely allows us to better observe the effect, indeed the higher you get, the greater the effect, and it is not difficult to get to high enough a vantage point that no instrument at all is needed to distinguish the effect.

Nice! That is an awesome way to measure Earth's circumference
