Night Sky Planispheres of Stars and Constellations- *The Night Sky is not just another planisphere. I think The Night Sky is the finest and easiest to use star finding aid in existence.*--Jack Horkheimer, T.V's Star Hustler. Conventional planispheres severely distort the sky near the southern horizon. The distortion results from trying to stretch the whole dome of the sky onto a single flat map. The Night Sky is NOT a conventional planisphere! No flat map can remove all distortion, but The Night Sky eliminates over 90% of the distortion inherent in conventional 1-sided planispheres. Various Latitude Ranges available listed below in degrees. Product Numbers vary. Click on item to view product number. Click here to order by fax, or phone!
