    A while back there was a discussion as to why the sextant was designed the
    way it was.
    It seems many have the handle at a 45d angle to the vertical and horizontal
    It also seems the most desirable bodies for shooting are between 30d and 60d
    above the Earth's horizon.  Average, 45d.
    Is it possible the handle is placed at 45d to facilitate swinging the arc
    near the 45d average line-of-sight to the body?
