    Duttons Navigation and Piloting 12th edition
    From: Bob Crawley

      Following a reference to this book in a Navlist post some while ago I found a copy. I wish I'd started Celestial Navigation with this book as it gives a very good explanation. It also covers a lot things I'd been curious about plus quite a lot I didn't know about such as:

    Correction for irradiation.
    Correction for air-sea temperature difference.
    Astigmatising shades - where can I get these?
    Chart projections, types and how they work.
    Differences in technique for Polar regions.
    Gyroscopic systems.
    Astro trackers.
    Doppler satellite navigation ( pre- GPS).
     
    All in all an excellent addition the library.
