Thirty three percent bigger than The Night Sky planisphere
on May 6, 2016
I bought this to replace my Night Sky planisphere because I found that it was a tad too small and difficult to read at night. The Guide to Stars is bigger, but not by as much as you might think. While it is physically almost twice as large, it extends further to the horizon, which is not that useful IMO. Spica is 85 mm from Polaris on The Night Sky planisphere, and 114mm on the Guide to Stars planisphere, about 33% larger. Personally I like the Night Sky planisphere because it's easier to hold in one hand while you are fumbling with eyepieces and focusers, but if you have any trouble reading fine print, I'd definitely go with the Guide to Stars.
