Even in the days of GPS one should know to find your position by classic celestial navigation. Just in case my GPS fails. Finally, I had some time on my last vacation and got a great book for that: Starpath, Celestial Navigation from David Burch.
Then I got back home and access to my Sextant and my 2010 Nautical Almanac I wanted to see if I can find my position. But the Sight Reduction Table is different to the ones I have in my study material.
It doesn't show Hc, d and Z but A/H, B/P and Z1/Z2. I also miss the SAME and CONTRARY part.
Who has an idea what to do?
