Cardboard versions of The Night Sky™ planisphere feature the same low-distortion, two-sided map projection as our plastic versions. The overall dimensions are 9″h x 8.5″ wide and feature a full sized 8″ diameter map.
The cardboard version is priced lower, but still exhibits superior durability. We have heard from owners who have been using the same cardboard version for twenty years! Some users tell us that they prefer the square dimensions and the ability to hole-punch the edge for insertion in a ringed binder.
