Hi Greg

There's a great podcast series, Astronomy161, which teaches about celestial navigation - including degrees, minutes, seconds, arcminutes, arcseconds etc. Well worth a download and listen.
You'll learn a lot more about a whole lot of things in Astronomy if you persist through the course. Very entertaining and enlightening.
