Hewitt,

I have not seen the Weem's secant table for time sights. I have seen the Rust diagram for azimuth which is not as good as Hanno Ix's azimuth diagram. The Weem's 9 page secant table for time sights sounds very interesting and could be combined with the Ix diagram to create an ultra compact sight reduction method.

Frank and Greg -

Have you seen Weems' The Secant Time Sight. Nine-page table and Rust for azimuth gives you an LOP. I used to have it in my sextant box for 'when else failz' backup. :-)
