The Night Sky 20°-30°N (Large) Star Finder Map – January 1, 1998
"Enlightenment Now: The Case for Reason, Science, Humanism, and Progress"
Is the world really falling apart? Is the ideal of progress obsolete? Cognitive scientist and public intellectual Steven Pinker urges us to step back from the gory headlines and prophecies of doom, and instead, follow the data: In seventy-five jaw-dropping graphs, Pinker shows that life, health, prosperity, safety, peace, knowledge, and happiness are on the rise.

From the Publisher
The Night Sky comes in two sizes: Large (8 inch diameter) and Small (5 inch diameter). The large size is best for learning the constellations. The small size is best as a pocket reference to tell you what constellations are up if you are already reasonably familiar with the constellations. In each size the charts are available for different latitude zones.
To find the correct size and latitude zone, use the following ISBN numbers in your Amazon.com search:
The Night Sky 50°-60° (Large), 1891938088 (Small), 1891938096
The Night Sky 40°-50° (Large), 0961320745 (Small), 1891938010

Now, let me tell you something that very few people know and that I only learned the hard way. Planispheres are constructed for specific latitudes. This one covers a band from 20 to 30 degrees north latitude. It is useful in Florida where I live as well as Texas. It would be of limited use for someone in oh, say Virginia and none at all in Massachusetts. There you would need a planisphere for 30 to 40 degrees north latitude. It is a very important distinction. So, if you decide to buy one, first find out the latitude where you live (you can find it on the Wikipedia page for your home state), then order the specific one for that latitude. It will save you a lot of headaches later
Almost like someone slipped the wrong star wheel into the thing, or I am really stupid at how to use this? Why is this so different from the online charts?
Edit: Belay my first attempt at a review, turns out I had no idea how to properly use the device. It is not like a starchart that I had been printing out. If there is a glitch with this product, it is that it does not come with a simple tutorial on how to use a planisphere. After months of staring at starcharts, I was thinking this was just a nice laminated version. Wrong.
It works as follows: there is an outter dial with the days of the year, and an inner dial with the hours of day. By aligning them, it is easy to see the stars that are on the sky at any day (night) and hour.
One side faces North and the other side faces South. It has the star coordinate system (the one in hours and degrees), so you can find planets, if you have a table that tells you where to look.
I think you should complement this with a book, such as "40 Nights to Knowing the Sky", in order to know what you are seeing.
