A new program has been released by Rodger Farley of Teacup Navigation which has more bells and whistles, including crossing multiple sights and stars sights. Rodger and I worked through a half dozen of our old sextant sights from the 70s to compare results and his program works to a tee. Furthermore, it produces accurate results for 2014/15 Check it out. It’s free.
