Bill,
Your video about the Bagnold Sun compass is fascinating! Your desert attire is perfect!
https://www.youtube.com/watch?v=N-YvH_dUW44
Perhaps because it's so simple to understand....I can't figure it out.
This much I can figure out-
1- Calculate or use a magnetic compass (adjust for variation) to determine the azimuth of the Sun.
2- Align the index figure (which is the Sun's azimuth) to the shadow cast by the gnomon.
Here's where I get "lost". Do I then adjust my course to that the shadow is on, let's say, 270° ?
Could you help further explain?
Great video!
Roland
