Agreed. My reply was intended to address just Geoffrey's question.
In addition to checking sight reductions, I have used Celestial Tools for sight planning -- enter a local time and your lat/long and it will give the approximate direction and elevation of every star. And it even gives you a choice of presentations of the information.
When sight planning with Celestial Tools you can limit the choices to just Magnitude 1 or better, Mag 2 or better, or all navigation stars. I live in the San Francisco Bay area and the light pollution here is so great it's almost impossible to see even Magnitude 2 stars much less anything fainter.
Celestial Tools is a really great suite of programs; I heartily recommend it to anyone doing CelNav.
