    You can estimate the height of the sun with your hand.
    When your hand is at arm's length, place you palm so that it's facing you
    and your fingers are horizontal. The width of your palm is approximately 10
    degrees. Place your other hand over your fist... now you have 20 degrees
    and so on.
    I use this to estimate the height of a body and preset the arc of the
    sextant... works quite well.
