Err...unfortunately, the camera lens will give a distorted image (thats why I suggested a base point of the bottom middle of ther picture). And that's why I suggested at least two more reference points, A simple straight line comperator is insufficient and may well result in an incorrect reading. The more reference points, the better.
You will probably have seen various historical films on the Royal Navy. When a sextant reading is taken, then more than one is taken by various people at the same time in order to get an average reading. The same principle applies here - if you want an accurate reading, then this is the only way to do it.
