Here is an ex-meridian back sight taken through a light haze to a sharp horizon while on an island mooring. What cove am I moored at ? This observation was extremely difficult even while on a mooring. Finding the Moon required observing the Moon to a short horizon then setting the sextant to 180 - the sextant reading. Even then getting the Moon into the field of view had me twisting about with my back to the Moon.
