Download and unpack the Hipparcos star catalog from www.astronexus.com/files/downloads/hygfull.csv.gz

Run in python to show interactive sky map with apparent star magnitude and approximate colour. 
About 90000 stars are plotted within a second, you can pan and zoom the view.

Run with "--interactive no" to generate a big PDF file for printing. I could not find anything with this
