As David Burch states it for StarPath: "SIGHT PLANNER that plots out the full sky in a radar-like view, showing heights and bearings of all bodies, from which you call a BEST SIGHTS function which displays the best triads of sights for that sky. Once sights are in hand, the SIGHT ANALYZER function fits sequences of data to the correct theoretical shape so navigators can identify the best sights of their set.

We would need to determine exactly what features are needed, but basically an overlay of the chart area with the current view of the stars and the preferred ones for sights..... or perhaps some minutes forward to prepare for taking sights. Then the ability to see the details for the selected star. Add it as a comparison, to the sight that is soon taken. https://friendsofthevigilance.org.uk/Astron/Astron.html

David Burch suggested lookiing at this program because it might help the programmer.

In his words:```

"There are also free utilities. A notable one is called Astron (British). https://friendsofthevigilance.org.uk/Astron/Astron.html

if you go there, enter lat lon time and date and then go to Planner tab at the bottom you will get a list of the bodies, Hc and Zn. All of his code is online, so i am guessing you or one of your experts could integrate that?
