Bubi,

If you fly east-west, you are bound to spend some time in sunlight.
Why not try a protractor with a plumb bob to measure the sun's
shadow.  This will be an inexpensive way to get started.  Of course,
if you fly north-south such as NA to SA you might be in the dark all
the way.  The A-12 sextant is the best way to go.  DO NOT buy an
A-10/ A-10A on eBay as all of these are inoperable, and are very hard
to fix.  Other than that, the A-10 is excellent, and better then the
A-12 for use in a cockpit.  As mentioned by another, there are many
discussions archived on the Nav List about aircraft sextants, and
also how to use them in flight.
