Three semesters of Celestial Nav plus Navigation Charting in 2 hours. This will be a very high-level introduction with lots of pictures, minimal mathematics. See how spherical trigonometry works then step outside, weather permitting, and "shoot" Aldebaran (Taurus), Sirius (Canus Major), and Pollux (Gemini).  Early arrivals might get a shot of Venus before it sets.

Ideally, celestial navigators have 4 things: Sextant, Chronometer, Ephemeris (like the Nautical Almanac), and a Sight-Reduction method (I'll mention 5).  Fortunately, there's a Free App for iPods, iPhones and iPads that does all of the above. You are encouraged to bring your device, after downloading AstroNav Lite by Sascha Troscheit.
