If I live at 40 degrees North latitude, do I purchase the 30-to-40-degree planisphere or the 40-to-50-degree planisphere?

Either planisphere will work just fine at 40 degrees North latitude. The more southerly 30-to-40-degree planisphere will offer a little more versatility, however, should you wish to travel to more southerly latitudes. As you go southward, you’ll see more southerly stars near your southern horizon that you don’t see from more northerly latitudes. But, as you travel northward, you DON'T see a greater number of northern stars – only a larger circle of circumpolar stars. Read about circumpolar stars here: http://earthsky.org/space/what-are-circumpolar-stars

For that reason, we recommend either planisphere if you plan to stay put, or the more southern planisphere for the traveling stargazer.
