Basic celestial navigation

I came across this fantastic introduction to the night sky today. I’ve browsed night sky books before and taken introductory astronomy, in which we got some practice identifying constellations in the night sky, but it’s always nice to get a refresher — especially for those of us immersed in city nightshine. I have to applaud the author of this particular resource, whoever he or she may be, for creating an experience that is informative, fun, interactive, and educational! Highly recommended.
