NavList:

Hello HermanD,

After years of working with Johannes (thenauticalalmanac.com) we know each other very well. He is indeed now a friend of mine and uses my software since years to generate what he publishes. I was also thinking along your lines ... that it might be a good idea to publish Lunars too. Well, I think we are a little beyond the year 1850, when Lunars quickly went "out of fashion" (replaced by marine chronometers). However I see a charm in studying or even employing the Lunar Distance method with solid good robust sextant. It's a challenge if ever there was one for yachsmen with a sextant.

With pleasure I'll pass your idea on to Johannes. Thanks for your feedback - and I welcome more feedback from this site. I can add that I did not even attempt to implement the "quadratic method" that Jorrit Visser described mathematically - however I used a far simpler approximation to determine the cut-off point when to drop ("invalidate") Lunar Distance angles when a celestial body passes close to the Moon. I rely on the experts here on NavList to correct me where necessary.

Kind Regards from Munich, Andrew
