Just want to point out that the graphical method for lat/long requires very little special math if that's a problem for people. However, I want to make sure I'm doing it right.
My fix was 5.7 km from where the navigator said (granted, the navigator has random error, only reports to arc minute precision and my map work is probably sloppy). But something happened that seemed different from the demonstration video during my map work. My 90 degree LOP line from the Betelgeuse azimuth transfer line actually crossed the azimuth transfer line from Polaris, which doesn't happen in the demonstration video. In the video, only the LOP lines cross. Is this normal, or did I mess something up? Sorry, if I'm messing up the terminology here too.
