Query: I'm enjoying it a lot.

It is very detailed. As it says, it's very similar to the stars you actually see in the sky.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.
