*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. Mini Planisphere Latitude Range: 30-40 degrees or 40-50 degrees North Latitude. Information on how to place your order by fax or by telephone. Product Numbers DCSPNS1 (30-40)and DCSPNS2 (40-50)
