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.
