So you bought one of our planispheres but haven't the foggiest as to how to use it. Or maybe you'd like some awesome information about planispheres in general. This website is very useful. If you scroll to a little after the middle of the page (where it says. "How to Use A Planisphere for Stargazing" in bold), it summarizes how to use planispheres, but really the whole thing is interesting to read.
