I think the nautical almanac has a simplified ("emergency") sight reduction table. I also recently found

Erik's Nautical Web Pages

To be handy.

It doesn't show Hc, d and Z but A/H, B/P and Z1/Z2.
Not sure what A/H etc. are. Maybe A/H is GHA? The Nautical Almanac tables I'm familiar with show GHA and Dec for each body, plus some extra corrections for the moon.

I also miss the SAME and CONTRARY part.
Two coordinates have the "same name" if they are both east or both west for longitude and hour angle, or if they are both north and both south for latitude and declination.

Who has an idea what to do?
My life doesn't depend on celestial navigation and I don't feel like paying for the book. I use "The Online Nautical Almanac"
