If you bring your sextant along, don't forget your chronometer, lots of navy books full of tables, plotting paper, straight edge, pencils, star identification chart, dividers? (I do not recall if you need a dividers to plot a celestial fix), etc.
I generally prefer navigation methods that also work on cloudy days since I do not have an Icelandic spar crystal.
