Navlist, at http://fer3.com/arc/ is a community of people from around the world who are fascinated by celestial navigation — and particularly celestial navigation as it was practiced 85 years ago...or 185 years ago.

• This is the place to be if you are interested in determining the time without a clock, by measuring the angular distance between the moon and a given star.
  
  

• Perhaps you are interested in what sort of sextants 747 airliners used to navigate across oceans back in the 60s.
  
  

• Or going further back in time, to learn how Francis Chichester used a marine sextant to navigate the first solo aircraft flight from New Zealand to Australia in 1931.
  
  

• Or you are interested in learning about how to use tables that were published decades before Pub. 249 came out.
  
  

• Or maybe you want to reduce sights without using tables at all...just using a slide rule.
