The Sextant - Noon Sight

In this episode Bob takes a noon sight, without a horizon, using both the Link A12 Bubble Sextant and the Davis M-25 Marine Sextant (using an artificial horizon). Despite not having access to the horizon, he was able to locate his position within just over 7 nautical miles. This is a sight done start to finish with all navigational calculations (well most of them, we could have done a bit better, but this is my house). Note, in order to provide an accurate location, the sextant requires two conditions to be true... 1/ light from the sun and stars must arrive at earth in parallel 2/ the surface of the earth must be curved (a sphere).
