This video is part 4 (and final) of the "Getting Started in Celestial Navigation" video series.
Part 4 of "Getting Started in Celestial Navigation," (The Pole Star) describes the process of finding, measuring, and reducing sights of Polaris (The North Star) to determine latitude at night in the northern hemisphere. Additionally, it talks about creating Universal Plotting Sheets for celestial fixes.
Here are some additional resources pertaining to this lesson:

The book I used to learn celestial navigation myself, and I think one of the best celestial navigation books out there, is "Common Sense Celestial Navigation" by Hewitt Schlereth - amazon.com/Commonsense-Celestial-Navigation-Hewitt-Schlereth/dp/0809272199
Produced and presented by Christopher D. Nolan, USCG cutterman (8 years) and US merchant mariner (500 ton Oceans). Currently on sabbatical aboard S/V Navigator.
