Not sure if this is the right place to tell you this, but no one wants to buy a pdf of a star chart. If I want a computer star chart I'll use a program to generate one live. It might not be as pretty as yours, but it's interactive.
Now if you actually printed large (huge?) format posters of the star chart you would have a market.
People would love to print a start chart as visible in a specific special place and time. It would be a great gift for weddings, birthdays, graduation, etc.
