I log in after a couple of years and see that people are still interested.
celestial nav was a primary means of navigating in WWII. Star sights would often be within a mile, and a good navigator would be within a fraction of a mile. Someone guessed at 50 mile accuracy, a navigator that far off would be keelhauled, There is an old thread where we were working on this.

I dont know if the program still works with Stellarium, but there is a lot of info and tutorials on how it works.
